TITLE: The Phase Diagram of the System NaF-BeF 2 (Diagramma sostoyaniya
sistemy NaF-BeF.)
PERIODICAL: Zhurnal neorganicheskoy khimii, 1958, Vol 3, Nr 11, pp 2562-2570
(USSR)
ABSTRACT: The system NaF-BeF 2 was investigated in the crystallization
range of beryllium fluoride. Purest sodium- and anmonium-
beryllium fluoride were used for the investigation: Na2BeF 4
and (NH 4)2 BeF 4* The differential thermal analysis was carried
out by means of the pyrometer by Kurnakov. It was found that in
the case of the thermal treatment of Na 2BeF 4 besides the thermal
effects at 220 and 3260C also an endothermal effect at 2700C
occurs on the thermograms. Na2 BeF4 melts at 610 + 500. The
results of the thermal analyses of the melt of the system
NaF-BeF2 are given in table 1. The phase diagram of the system
Card 112 is given in figure 1. The following double salts were found to

The Phase Diagram of the System NaF-BeF 2
occur in the system: 3 HaP.BeF 2 (decomposes at 4600C)l 2NaF.Be F2
(m lting point at 6100C), NaF.BeF 2 or 1qaBeF3(melting point at
38000, NaF.2 BeF 2 (decomposes at 27000%
Thermal analyses of the melts were carried out with 33,3 - 50
mol,4 BeF2as well as with 50 - 100 mol% BeF 2- On the strength
of the investiCations carried out a second phase diagram of
NaF-BeF2 was constructed on which also the limit of the hiGh-
temperature modification is plct-ted.. The structure of the high-
temperature modification of beryllium fluoride was not determined.
The melting point of this modification is 8000C.
There are 8 figures, 4 tables, and 17 references, 9 of which
are Soviet.

TITLE: Dielec ric an Calorimetric Study of Ammonium Sulfate- and
Ammonium Fluoroberylla rystals
PERIODICAL, Izvestlya Akademll nauk SR. Seriya fizicheskaya, 1960,
Vol. 24, No- 10, PP- 1228-1230
TEXT; Large ammonium sulfate monoorystals were obtained from an aqueous
solution of the chemically pure reagent by applying the cooling method.
Ammonium fluorobaryllate was synthesized by Lebeau's method (Ref. 5).
The crystals were bred from its aqueous solution by evaporating at a con-
stant temperature. Studied dielectrically were c-cuts of OTH 4)2SO4 crys-
tals and b-cute of (NH 4)2BeF 4 crystals. The crystalline powder used for
the crystal breading was studied calorimetri,~aily~ e and tan 6 were meas-
ured after all stabilization processes were over. Temperature dependences
of Z and tan 6 are shown in Fig. I for the c-cut of (NH 4)2 so4crystals,

and in Fig. 2 for the b-cut or(NH 4)2 BeF4crystals. The dependences tan 6(T)
have the same character in both crystal types. E (T), on the contrary,
exhibit considerable differences, The authors also considered temperature
dependences of polarization for different field strengths in the region of
phase transformations of the mentioned crystals. The respective results
are published in a separate article. Fig. 3 shows the temperature depen-
dence of specific heat c P for (NH 4)2 so 4' It was found that the cooling
of the specimens at T > T K is not always accompanied by their transition
into the piezoe lectric phase. The undercooling was determined as being
about 0.4 4 0.5 , which corresponds to dielectric measurement results.
The mean value of integral temperature of transition was 490 cal/mole.The
temperature dependence of c p on (NH 4)2 BeF4is given in Fig. 4. The curve
shows a characteristic A-peak. No undercooling effect was observed. The
discrepancy between the transition temperatures determined calorimetrical-
ly (19.9 and -98.60C) and those determined dielectrically (.47.6 and
-93.4 C) is probably to be explained by an inaccurate graduation of the

differential thermal analysis of the mo-Hen,iiow cooled mixtures of pure components
of the system to determine the conditions o ormation of fluoroberyllate glaoses./f
The formation of such glasses was reported in the literature. A rapid (30-40C

glasses over the entire range of concentrations of the components. Quality of thet,~

Periodical : Teploenergetika,3 9, 28-35, S 1956
Abstract : The problem of designing a turbine stage with a constant
pressure along the radius is discus-~ed. The authors
demonstrate theoretically that a solution is possible with
the help of regular cylindrical blades, but only at the
expense of an appropriate design of the main section of
the turbine. These theoretical considerations are con-
firmed by experimental data. Definite deductions must be
made after the testing of a turbine with a revolving
wheel. 7 diagrams. 3 references.

TITLE: The Flow Separation Phenomena in Annular Grids
PERIODICAL: Izvestiya vysshikh uchebnykh zavedeniy, Energetika,
1958, Nr 11, pp 92-108 (USSR)
ABSTRACT: The experimental investigations of isolated annular
grids with relatively small D/1 values show phenomena
of flow separation from the hub in the space behind
the annular grid. These phenomena are observed inside
the grid itself at very small D/1 values. These phe-
nomena might cause fear that the flow separation will
occur also in operational turbine stages. Further
they might lead to doubt in using experimental data
obtained during annular grid tests for analyzing
the funtion of a turbine stage. K. Bammert and H.
KlAukens Zffef 17 explained for the first time theo-
retically the flow separation from the hub, applicable
to turbineal suing the principle of the "maximum flow"
Card 1/5 or the "minimum pressure drop". They used a number of

The Flow Separation Phenomena in Annular Grids SOV/143-58-11-13/16
assumptions for simplification: 1) A cylindrical
flow was assumed behind the outlet section of the
grid (Section I, as shown in figure 1b) and in thp
zone of maximum flow separation development (section
11). 2) An ideal liquid was taken into consideration,
permitting the assumption of a constant pressure at
the flow separation boundary. 3) An incompressible
liquid was considered. 4) A sufficiently long section
of a cylindrical tube was assumed behind the annular
gridl permitting a free development of the flow se-
paration zone. The authors of this pEfper investigated
in which way the aforementioned solution will corre-
spond to actual conditions and studied for this reason
a number of factors influencing the flow separation
phenomena. The assumptions of the cylindrical flow
behin the grid and in the far section,.in the area of
maximum stagnation zone development, leads to some
contradictions. Inventigating the influence of the
meridional curvature, the authors state that it is
necessary to abandon the assumption of the cylindrical
Card 2/5 flow in sections I and II (Figure lb). It is more

The Flow Separation Phenomena in Annular Grids SOV/143-58-11-13/16
natural to assume a flow curved in the meridional
plane in the outlet section of the grid, considering
it as a cylindrical flow in section II, which also
corresponds to experimental data. The results of
the calculations conducted by the authors show: 1) The
curvature of the meridional trajectory at the outlet
section of the annular grid changes sharply in depend-
ence of the hub ratio and the angle a , as shown in
a graph, figure 2. With increased hui ratio, the
magnitude of radial acceleration, or more accurately,
the change of radial velocity cjr,.is reduced along
zo turning to zero at a critics. b ratio. The lat-
ter depends on the angle a . 2) The radius of the
stagnation zone In the area, where the flow already
may be considered as being cylindrical, decreanes ea-
sentially with an increaoin angle 0- and depends very
little on the hub ratio. 3~ The prJoure of a meridi-
onal trajectory curvature in the outlet section of
the grid leads to a disturbance of the law of velocity
Card 3/5 component changes on the radius. 4) The deviation

The Flow Separation Phenomena in Annular Grids SOV/143-58-11-13/16
of the flow characteristic distribution in section
I leads to a very strong disturbance of the law of
velocity component changes in section 11. 5) The low
parameter distribution on the radius in section I de-
pends on the flow coneA.tions in section II. The state-
ment in Lffef 17 that vhe working blades are not fully
used in stages with lengthened blades at small angles
OL , requires checking. The authors investigate the
iniluences of increased pressure at the flow aepara-
tion boundary, compressibility and twist. For the
experimental investigation a wind tunnel with turbine
blade grids Nr 1 and Nr 2 and an air turbine with
grid Nr 3 were used. The data for these grids are
listed in table 1. The authors present the experiment-
al investigation results in 19 graphs, dealing with
meridional flow lines, static pressure changes and
distribution, the influence of flow conditions on
the annular grid and the component velocity profile.
For the 'theoretical investigation certain assumptions
were made concerning the liquid flow behind the annular
Card 4/5 grid. One of the most essential errors is caused by

The Flow Separation Phenomena in Annular Grids SOV/143-58-11-13/16
assuming the absence of viscosity. However, tnking
into consideration theoretically the influence of
viscosity on separation phenomena is very complicated.
The fact that the actual border of the stagnation ,
area is below the theoretical one, may be explained by
the viscous interaction betwwn the basic flow and the
stagnation area. As a result, the axial velocity is
considerably reduced while the section of the basic
flow is increased. In this way, the presence of vis-
cosity in some way increases the flow stability.

made using three F-shaped tubes which made It possible to reach the walls as
close as 0.5 mm. Due to considerable stage irregularities and inadequate preci-
sion In the assembly of the nozzle grid, the "traversirovaniye" along the circun-

TFM The application of wide clearances between rims Is made very tempt-
Ing by the adjustment of the pitch Irregularity In the flow with Increasing dis-
tances from the nozzle cascade, especially for gas turbines, where the ahnence
of shroud rings deteriorates the blade vibration characteristics. However, In-
creasing the clearance between the rims can lead to additional losses. Contra-
dIctory experimental data published by various authors (Refs. 1, 2 and 3) show
that this effect has not yet been sufficiently studied. For example, experimmts
at MAN (MAI) show a 7 - 15% efficiency Increase upon enlarging the clearance be-
tween rims by 7 mm. This result is hardly justified, since it would mean a 25 -
50 efficiency increase of the working blades. The authors present the results

dial clearance in the periphery was 0.75 mm at a blade height of 81.5 mm. The
same turbine stage, and partially the same experiments , were used like in the
experiments described by the authors in a previous paper (Ref- 5). The results
of the Investigation are compiled in 9 graphs. The authors arrived at the fol-
lowing conclusions (valid only for the given turbine stage)s 1) With increasing
distances from the nozzle cascade, the flow energy decreases essentially, mainly
because of losses at the flow borders. 2) From the view point of losses at the
working blade an optimum value In found for the clearance between the rims at
which the pit:~ irregularity of the flow has already been sufficiently adjusted,
while the radial Irregularity is not yet sufficiently developed due to a deviat-
ing of the boundary layers- 3) Losses in the outlet velocity caused by a dis-
placement of thA flow towards the periphery and the formation of a stagnation
zone at the blade root are distributed very irregularly over the radius and con-
stitute a very essential magnitude. 4) The presence of a negative degree of re-
activity at the blade root causes a considerable efficiency reduction of the

The experimental investigation ... A005/A105
The measuring method Is expounded. The pictures of the meridional lines of flow
behind the annular cascades as well as the graphs of curvature of the merldional
lines of flow, of the radial differences In pressure, and of the radii of the
separation zone are presented. The results obtained are compared with the calcu-
lation data. The experimental data on the velocity profiles and the angles 00
behind the annular cascades are presented. It Is poInted out that the flow
behind the annular cascade may relatively be divided into three zones: 1) the
zone Immediately behind the cascade, where the separation did not yet proceed,
and the radial velocity is small, but the curvature of the meridional trajectory
has a maximum; 2) the transition zone; 3) the zone of cylindric flow after
the finishing of flow shift Into the periphery and formation of the dead zone.
The experimental data are compared with the calculation results according to the
Bammert-KIlukens method as well as the refined method of the authors (see abstract
3B147).' For explaining the effect of the flow conditions behind the annular
cascade an the flow in the cascade, an investigation was carried out by means of
a restrictor disk with radial slits of constant width. The separation zone was
sharply reduced. Results from the investigation of cascade no. 3 together with
the impeller with cylindric blades of the T-1 profile are presented, and the data
obtained are analyzed. A. Bunimovich

ABSTRACT: The article is a further development of P. A. Romanenko's earlier
work (Ix.v. AN SSSR. Energetika i avtomatika, 1959, no. 6). A method is act
forth for calculating the distribution of cylindricV,, -stream parameters in a
turbine stage with an allowance for the region occupied by the rotor blades and the
ring space beyond these blades* Three variants of the stages of an experimental

air turbine were calculated by the above method with a view toward investigating
the effect of the movable-blade twist on the flow beyond the nozzle raw. The
blade length, 8 1. 5 mm, and outside diameter, 500 mm. were kept constants, the
twist pattern and nozzle -diaphragm width were varied. The latter parameter was
found to have the strongest influence on the stream distribution. Origi art@ has:

The article presents the results of an experimental investigation of the
break down of the cylindrical charao~er of the flow in turbine atagest
with different degrees of twisting, maintaining strictly cylindrical
characteristics of the flow through section, Results, given In a series
of curves, show that in general the radial gradient of the reactivit7 in
a stage with cylindrical boundaries of the flow through section does not
obey the simplified equilibrium condition. In particular, In stages wit
vanes of a constant profile,, this lack of agreement is very noticeable*
A considerable break down of cylindrical flow can take place even with
small inter-rim distances. Orig, art* has: 5 formulas, 6 figures and

ABSTRACT: An investigation has been made of the effect of cyclic heat
treatment (CHT) on the internal stresses and relaxation characteristics
of alloys containing phases with different expansion coefficients.
Each cycle in CRT consisted of cooling to subzero temperaturee (-40 to
-190), holding for 10-120 min, followed by heating to relatively lov
temperatures (up to 150C) and 'holding at these temperatures for 15- 240
min, It was found that CHT reduced internal stresses and increased the
relaxation strength in all investigated alloys. The greatest decrease
in internal stresses was observed in AL2 (12.1%81) and AL9T2 (T%Si, 0.3%
Mg) aluminum alloys, The CRT had no effect on the tensile and yield
