TITLE: The PT-projection of the Alumina-water System
(PT-proyektsiya sistemy kremnezem-voda)
PERIODICAL: Doklady Akademii nauk SSSR, 1959, Vol 126, Nr 3,
pp 645-6-16 (USSR)
ABSTRACT: The system mentioned in the title is a limiting system for
many silicate systems with volatile components which are of
importance in petrology and mineralogy. At least 5 phases exist
in this binary system at high temperatures: cristobalite,
tridymite, quartz, liquid and vapor. It is (accordinF tn
Ref 1) a multiple system with'one degree of freedom.
In general, such system mnst have 5 invariant points and 10
monovariant lines. The pr-):~ent case is simplified by the
circumstance that all cryst%iline phases are of the same
chemical composition, and only the monovariant reactions
(1)-(6) are possible between the phases. In the reactions
M-(6) the liquid and gaseous phases do not take part, so that
the equilibriums are degenerated. This simplifies very much
Card 1/3 the building-up of a basic scheme for the system mentioned in

The PT-projection of the Alumina-water Syotem SOV/20-126-~-52/69
the title (Fig 1). All 3-phace monovariant equillbrilims :ire
stable in this scheme. This 13 in agreement with the oxve_-iment.
In the present case, the degenerated equilibriums are stable
on both sides of the invariant points. The corresponding
curves pass over into one another without changinp, their
directions. The variant, in which the equilibrium trid,,-mite +
+ gas = melt is unstable, is excluded from considerat-'~)n. kn
experiment, however, makes it easily clear that tridymite
can coexist with the melt. As the experimental PT-diagrp:n of
the mentioned system (Ref 2) is incomplete, and does not agree
with the theoretical scheme (Fig 1), the authors achieved
some precision and completion by their experiments. The
resulting experimental PT-diagram corresponds to the
theoretical scheme (Fig 1). Figure 2 shows this experimental
diagram (Refs 3, 4). A comparison of this diagram with the
material found by other investigators shows differences in
the position of various points and lines. There are 2 figures
and 4 references, 1 of which is Soviet.

TITLE: The Equilibrium Temperature of Slender Bodies in
SuRersonic Flow\
PERIODICAL: Izvestiya vysshikh uchebnykh zavedeniy, Aviatsionnaya
tekhnika, 1960, Nr 1, PP 35-42 (USSR)
ABSTRACT: In this paper the corrections are discussed which must
be made to the heat transfe4coefficients ~1 a flat 6
plate in order to apply them to thin wedgeg"and cones2-
at high supersonic velocities. First of all, an
approximation is introduced for the heat transfer
coefficient of a flat plate. From this the effect of
the shape of the body on the heat flow can be expressed
in the form of a factor. The expression obtained for
the heat flow is used to reduce the determination of the
equilibrium temperature to a single graph, which is
given in the paper. It is assumed that for slender
bodies the effect of compressibility on heat transfer
Card 1/6 is expressed by the variation of the density and viscosity

The Equilibrium Temperature of Slender Bodies in Supersonic Flow
in the boundary layer, neglecting the effect of
compressibility on the structure of the latter. An
expression is found for the effect of Mach number on
the boundary layer and of a flat plate and this is
replaced by a simple empirical expression involving
the concept of equivalent temperature, which is a
linear combination of the wall temperature, the
temperature on the edge of the boundary layer and the
stagnation temperature. Both lam�nar and turbulent
boundary layers are considered and the weights in
the linear combinations differ in each case, both
being derived from experiment. The results obtained
so far are now applied to slender bodies, a wedge,
thin profile, slender cones and slender bodies of
revolution being specially considered. FinalLy, the
determInation of the radiation equilibrium temperature
is discussed. Starting with the approximate
exprassions for the flat plate (Eqs I and 2), and
Card 2/6 assuming that the compressibility phenomena result

The Equilibrium Temperature of Slender Bodies in Supersonic Flow
only in the change of density and velocity of the
gas inside the boundary layer (this is trite in the
case of a flat plate everywhere, while for the slender
bodies it breaks down in the regions of strong
interaction between the shock wave and the boundary
layer, i.e. near the nose of the body), Eq (3) is
derived in which the expression in square brackets
denotes the effect of the Mach number M on the
boundary layer. Employing now the fact that pressure
across the boundary layer is constant and adopting the
approximate variation of viscosity with temperature,
Eq (4) is obtained. The effective temperature is the
function of the temperature of the wall (T W),
stagnation temperature (Tr) and the temperature at the
outer edge of the boundary layer (T6) as given by
Eq (5) in which a,b and c are some constants. (This
equation is equivalent to the corresponding relations
given by Karman, Tekker, Young, Rubezin and others).
Card 3/6 The constants are determined by applying Eqs (3) to

The Equilibrium Temperature of Slender Bodies in Supersonic Flow
to the flat plate and utilizing Eq (6). The experintonts
and more accurate formulae (Ref 1) confirm that it may
be taken that a:b:c = 4:3:2. In Fig I the graphs of
Eq (5) with the above values of a, b and c are compared
with the corresponding more exact relation based on
Karmen's similarity principle (Ref 1), while Fig 2
relates the experimental data available with the
relation of Eq (6) and a similar relation of Ref 2.
Agreement is quite satisfactory. As seen from this
figure, even if it is assumed that a=b=c (full line
in the graph) the result does not differ much from the
experimental data. The above results apply to the case
of the boundary layer being turbulent; when the boundary
layer is laminar the coefficients will be a:b:c = 0.271
0.55:0.18. Hence the approximate coefficients of heat
transfer for the case of the flat plate are given by
Eq (7) when -the boundary layer is turbulent ftnd Eq (8)
when the boundary layer is laminar. For the case of

respectively.

ABSTRACT: The effect of near-zero and zero gravity on the process of bubble formatioq
(bubbling process) in a flow of gas injected into a liquid through a tube is consid-
ered.Flows of gas into stationary and moving liquids are analyzed for various values
of Bond and Weber numbers under conditions of weightlessness. Conditions are estab-
lished under which the bubbles may break away from the tube. The main parameter
characterizing the process, the ratio D/d where D is the diameter of a bubble at the
time of breaking away and d the diameter of the tube, is expressed in terms of the
Bond number. The analysis shows that the absence of mass forces and even the un-
fayorable direction of g forces can be compensated by the motion of the fluid under
specific conditions. The Interaction bctween a forming bubb1c --..;d an already detacbeC.
bubble, that'is, between pulsating and oscillating bubbles in Wltliquid is evaluated by.

density change during compaction and is -an elastoplastic-
medium in which uniaxial deformation is governed by the piecewise-

ABSTRACT: The second author proved (reference 1) that with zirconiur-
-extraction frora perchloric acid containine solutions HC10
passes over in analyzable quantities. Their complex-formatii,
with TBPh was worth investigating in view of their application
for the maintenance of a constant -Jonic density. Perchloric
acid was extracted from water by TBPh oolution in benzene or
petroleum. The phases were equal with all teats (23 ml). The
equilibrium was attained within 10 to 15 minutes. Tn tests on
the distribution of perchloric acid between water and 3,67
mol TBPh it was found that with increasing concentration of
HC104 in the initial solution the quantity pasain& over into

an exothermic reaction takes place which is most intensely in
the case of stronger acid solutions (table 1, test 6). it was
tried to compute the equilibrium constant of the reaction of,
complex-formation of HC10 with TBPh (KO , from tl,,.e obtained
results. It is shown in thle 1 that Ki is variable within vast
limits. This is apparently achieved by the ionic density of
the solution which flud;uates under the influence of the chan-
ges of concentration of the acid. With a constant ignic densi-
ty K1 remains sufficiently constant (6,7 � 0,5),10-'-. In this
case the equilibrium constant of the reaction of complex for-
mation of HITO with TBPh(K2) amounts to 0,16 + 0,01 (table 2).
The K2- value is neither changed by usin.- solitions which are
diluted by benzene or petroleum, if the ionic density of the
solution is preserved (,,3) (table 3, 4). The value of K in-
creases with diluting the TBPh-solution3 Up to 0,22 � 0162
(little different from references 3 to 6). It is noticeable
that the TB~h-dilution with petroleum lead to the formation
of a third phase after the extraction if the HITO -content in
the initiallisolution was small, compared with that of HC10 4
(table 4, -Vast 1). The light organic phase (d250 - 0,750) is

676-68o
TEYT: Diborides of Ti, Zr, Xb Ta and Cr, and also MoDB5 were
6Lud ic!,j. The N-YR signal from ~11 was observed at 6866 kcs in a
",Iaz-~nctic field of 5030 oersted, using an RF spectrometer
previously described. The field nonuniformity within the 2 cm3
sample did not exceed 0.1 oersted. Samples were 99% pure and
approaching stoichiometric composition. In all the compounds
X-ray phase analysis showed the presence of single phase. The
quadrupole bond constant BI was measured from the distance of
the two satellite lines and the (strong) central line. Except
for CrB2 and ~10-1135, the satellites were observed directly; -in
the case of CrB0, the secondary effects of the strong quadrupole
in~_eraction made the value of B very inaccurate. The
satellite Of 1"102B5 was not found in the range 0 < B < 200 kcs,

The authors studied also the change in the physical properties
when a boride is formed from the respective metal and when one
metal replaces another in the boride molecule. The former
reaction was attributed to the filling of che incomplete d-shell.
I formation is responsible for a negative Hall constant,

These relations were further exei-,iplified on a plot of relative
melting points of diborides, It was concluded that in common
with moriocarbides and mononitrides, the diborides undergo
characteristic filling of the d-shell of the transitional metal
with the valeacy electrons of the metalloid atoms. There are

TITLE: Motion of gas bubles caused by pressure fluctuations in the liquid in the absence of mass
forces
PERIODICAL: Zhurnal prikladnoy mcklianiki i tcklmicheskoy fiziki, no. 3, 1962,-3-9
TEXT: The paper extends the Bjerkness-Zhukovskiy analysis of the force of interaction between fluctuating
spheres to the case of motion of gas bubbles caused by pressure fluctuations. The translational motion of two
gas bubbles, suspended in a liquid occupying a spherical volume on whose external surface acts a fluctuating
pressure p(t), is examined. The Lagrangian equations of motion are integrated for the case p(t) = po i- p sin mt
under some simplifying assumptions and neglecting the mass forces. The results obtained are extended to the
case of a liquid contained in a vessel of arbitrary shape, and also to the case of an unique bubble placed near
the vessel wall. There is I figure.

TITLE: Radio-chemical telomerization of olefines
PERIODICAL: Neftekhimiya, v.2, no.4, 1962, .617-623
TEXT: Additional data are presented on the tolomerization
between ethylene and carbon tetrachloride, and the reaction between
tetrafluoroethylene and isopropylalcohol. The experiments were
conducted in a thermostatically controlled autoclave at 16 to
100 atm pressure in the absence of oxygen *60 The ethylene- CC14
mixture was irradiated with y-rays from C. with the activity
of about 350 g/equiv radium. The activity of the source for the
C2H2F4- alcohol mixture was 120 g/equiv radium. The molar ratio
C2H4- CC14 was varied from 0.2:1 to 3.8:1 and the reaction was.
studied at 20, 50 and 100"C. It was established that the content
of individual telomers in the reaction product is given by the
following approximate equations
Fl -- ClR F = C2R - ; F3 = (c C3R
CIR+ 1 2 (CIR + 1) (C2R + 1) lR + 1) (C2R + 1) (C3R+ 1)

Radi-chemical telomerization ... E075/E435
where Fn is the niolar proportion of telomer with n olefine
residues, Cn - the chain transfer constant for the radical
leading to the formation of telomer with n olefine residues and
R - the niolar ratio of telogen to olefine in the reaction mixture,
When the ratio is changed from 3.8:1 to 0.2:1, a marked increase in
the yield of tetrachlorapropane is observed (from 3 to 5q/ to
63 to 1000C). The results were used in the development of radio-
chemical plant with an output of 8 kg/hour of tetrachloroallcanes
with Co source activity of about 15000 g/equiv radium in a reactor
of 0.5 m3 volume and 800 min in diameter. Telomerizati-:,r. between
C2H2F4 and lower alcohols was studied at room temperature. The
radio-chemical yield decreases in the series propanol-2 >
butanol-I \, ethanol > butanol-2 > methanol. The reaction
conditions were selected so as to eliminate completely the
formation of high molecular weight compounds. There are 4 figures
and 2 tables.
