By the work carried out in the laboratory for the physics of extremely high
pressure of the USSR Academy of Science concerning the construction of com-
pressors for extremely high pressures it was possible to develop a continu-
ously operating machine which is able to eject water through a nozzle of from
0,2 to 0,8 mm diameter at pressures (prevailing before the nozzle) of up to
1500 atm. As such a pressure drop before and behind the nozzle requires great
t efficiency of the hydraulic compressor, it was necessary to build a machine
e, that performed at least 1000 revolutions per minute and that was able at pres-
oc sures of up to 2000 atm to produce one ton of water per hour.
The authors carried out their tests at pressures below 1500 atm in ordbr to
a diminish the part played by the boundary layer introducing the jet of liquid.
They used nozzles of at least 0,45 mm diameter; shape and surface of the noz-
P.r< zle exercise considerable influence on the disintegration of the jet of liquid.
The most favorable shape of the nozzle is shown in form of a drawing. On this
XmS, occasion it was not possible to use any of the existing methods for the direct
measuring of the jet velocity, and it was necessary to use the BERNOULLI

ABSTRACT In the laboratory for the physics of super-high-pressures of the Academy
of Science of the U.S.S.R. a permanently operating machine is established,
by means of which a continuous water jet which is previously compressed
up to 2000 - 2500 atm. overpressure, and*then emerges from a round pro-
filed aperture of 0.2 - 1.24 mm diameter, is obtained. In order to ob-
tain a continuous waterjet at a pr6siure of 2000 - 2500 atm. overpressure,
which corresponds to a jet-valocity of 600 - 650 m/sec-1 it was necessary
to construct a fast-running machine (1000 wave-revolutions/min.) with an
electromotor of 240 kff. Two models of such a machine were constructed.
One of them had an output of 1200 1 p.h. with a consumption of 20 - 85 kW
at different pressures, the other had an output of 1800 1 p.h. at 110 -
120 kW and approximately 2000 atm. overpressure. Different jet-diameiers
facilitated the modification of the pressures before the jet. The jet
has behind the conical part with a certain narrowing angle a cylindrical
part of a certain length. The inner surface must be carefully polished.
According to Bernoulli, the velocity for a perfect incompressible and for
a compressible liquid in dependence on the pressure was calculated and

shown in a diagram. The general character of the passage of a jet through
the atmosphere was determined. It turned out that, with an increase of
jet-velocity beyond sound-velocity in air, the water-jet becomes more
compact, the conical aperture-angle, however, decreases. The thermal
effects occuring on the occa3ion of throttling become compensated in a
certain degree. On the occasion of throtteling a compressed liquid a
heat-effect viz. the Joule-Tomson-offect is produced. Experiments show
that the liquid ejected from the jet actually becomes heated. It is tho
author's opinion that the only reason for the existence of a limit for
the experimentally, obtainable velocity of a water-jet ejected under
pressure from a jet is due to the Joule-Tomson-effect, for, at a certain
pressure, temperature rises to such an extent that the water evaporates.

in which was stated that in the case of a 6 liter (volume)
the fluctuations of pressure in front of the nozzle at a
total pressure of 2000 atmospheres do not exceed 10 %. But
at a hiGh velocity of jet, about 500-600 m/sec, an estimation
of the friction produced on the metal wall is very difficult.
For this purpose the attempt was made.to determine by
experiment the dependence of the water-jet friction at the
nozzle wall on the diameter and on the quantity of pressure

from the nozzle. There are 2 figures and 3 references, all

ABSTRACT: Here a theoretical computation Df the dependence of the pressure-
pulsation-smoothing degree in the receiver on the capacity of at
pressure production in this receiver by means of a hydraulic ultra-
high-pressure compressor was carried out. The influence of the re-
ceiver-capacity (contents) on the pressure-pulsation-smoothing de-
gree in the receiver is investigated by experiment. The results of
the computation were compared with those of the experiment with re-
gard to the pressure-pulsation-smoothing degree of the water in
the receiver and it was ascertained that the theoretical computa-
tion in spite of a number of simplifying assumptions shows a satis-
fyin*onformity with the data of the experiments. On account of the
results of the experiments the wate 'r jet, which flows out of a 5-6
liter receiver at supersonic velocity, may be looked uDon as well
smoothed with regard to the impulse-pressures and consequently also
with regard to the impulse-velocities.There are 5 figures, 2 tab-
les and 3 Slavic references.

ABSTRACT: This paper covers the investigation of a continuous horizontal
fluid jet at sub- and supersonic velocity (from 300 to
540 m/sec). The principal procedure adopted in the experiments
is described. In order to obtain a jet with the required para-
meters, the Nr 1 hjdraulic plant of the association mentioned
below (Ref 7) was used. The distribution of momentum in a con-
tinuous water jet ejected at supersonic velocities from a
nozzle was obtained. According to the curves describing the
momentum distributioTi the boundaries of a free water jet moving
with supersonic velocity in the atmosjhere were determined. The
contour of the jet is in accordance with that observed in pho-
tographs. It was found that an increased viscosity of the fluid

section of the ejector. The active fluid is supplied by the hydraiilic compressor
through nozzle I with a central angle of taper of 500 and a cylindrical section
with a length-to-diameter ratio of 2.5. The fluid discharge through the nozzle
amounts to 0.45 liter/sec. The passive fluid is supplied by the OK-5-15M (LK-5-
15M) centrifugal pump to receiver 2 and enters mixing chamber 3 through a ring-
shaped slot 10.3 mm in diameter. The pressure of the passive fluid is controlled
by a damping pressure gage through connecting branch 4. The mixing chamber,
consisting of the conical input part with a central angle of taper of 50 0, the
cylindrical neck 6.94 mm in diameter and the conical diffusor with a span angle
of 80, is of solid construction and polished. From the diffusor the fluid gets
into the cylindrical receiver 5, 15 mm-in diameter where the output pressure is
measured by a damping pressure gage through connecting branch 6. The ejector
parts are made of 45XHI'I-;)A (4~KbNIMFA) steel, 'the seals are of teflon.. The oxttkut
pressure and the total fluid discharge are controlled by a valve. At an output
pressure of 30 kg/cm2 the ratio of passive fluid discharge to active ftuid dis-
charge is 2:1. The following technical data are given: pressure fluid - water;
nozzle diameter - 1.15 mm; neck diameter 6.94 mm; pressure of active fluid

TEXT: Peculiamities and rules of ejector are investigated at a pressure of
the active liquid (pi) between 300 and 1,000 kg/cm2, and a presnure of the
passive liquid (p2) between I and 7.6 atmospheres. A diagram of the experi-
;aental Dlant is shown by Fig. 1. By exchanging the central ejector part,
discharge parts with different diameters could be investigated. The ex-
perimental results are Given in Figs. 2 and 3. As can be seen, the charac-
teristic of the ejector consists of a working and a cavitation (vertical)
part. The limit of the ejection coefficient q* is determined by the pres-
sures p, and P2 as well as by the form and size of the discharge part. An

increase in p, leads to an approximately proportional pressure increase
behind the ejector, at the same time shifting the beginning of cavitation in
the direction of lower q-values. The change in P2 influences only slightly -
the working characteristic but the more so the critical ejection coefficient.
The critical ejection coefficient is well expressed by the formula

permits a determination of the position of the cavitation branch of the
characteristic. The formation of cavitation was observed visually. Fig. 4

PERIODICAL: Inzhene:rno-fizicheskiy zhurnal, 1960, Vol. 3, No. 3,
pp. 87-90
TEXT% The formation of cavities by quickly moved liquids is investigated.
Among other things, the authors refer to the opinion expressed by
yl~ Kornfel"'d (Ref. 3), according to which the destructive effect is caused
immediately by the water hitting the metal surface. Besides this purely
mechanical theory of the effect produced by cavitationg also the chemical
theory is mentioned. Experimental results, in which the time-dependence of
the formation of cavities on various factors was investigated, are discussed.
As may be seen from Fig. 2, the time for the formation of cavities decreases
sharply with increasing velocity. Fig. 3 graphically shows the dependence
of ih.9 time required for the formation of ca:7ities upon the distance be-

PERIODICAL: Doklady Akademii nauk SSSR, 1961, Vol. 136, No. 2, pp. 320-321
TEXT: The authors studied the resistivity of antimony, arsenic, and
2
calcium at pressures of up to 200 000 kg/cm . Likewise, bismuth, whose
2
resistivity has hitherto been known up to 140 000 kg/cm , was investigated.
The bismuth and calcium specimens were made from wire, the antimony and
arsenic specimens were thin single crystals. All specimens were chemically
pure. As may be seen from changes in resistivity of the specimens graphi-
cally represented in Figs. 1, 2, and 3, arsenic and calcium have a mono-
tonic change of resistivity with rising pressure, bismuth and antimony,
however, have not. At 130 000 kg/cm 2, antimony shows a jump-like change

TEXT: This is in continuation of an earlier paper by Vereshchagin et al
(DAN, 136, no. 2, (iq6i)), The authors wanted to find new polymorphous'
transformations at high pressures in metals being accompanied by an abrupt
change of resistivity. Bridgman (Proc. Am. Acad. Arts and Sci., 81, 165
(1952)) and Bundy (Phys. Rev., 110, no., 2, (1958)) have been able to
identify a corsiderable number of polymorphous transformations of various
metals and alloys at high pressures,, The possibility is pointed out of
calibrating high-pressure apparatus with the aid of an abrupt change of
the resistivity c'L different alloys at given pressures. The authors used
a high-.pressure chamber calibrated with the aid of the known resistivity

were wires 0.6 --0.8 mm in diameter, the medium trar!smitting the pressure
was silver chloride. Measurements were conducted at room temDerature.
Measurement results are graphically presented in, Fig. 2, R 30 is2the

Bridgman discovered on zirconium at a pressure above 80,000 kg/Om2 a sharp
drop of the resistivity. The authors have not been able to ascertain this
2
drop up to 250,000 kg/cm . The difference in results is explained by a
possible difference in the purity degree of the metals. The authors used
zirconium iodide with 99.7 ~o purity. The following comparative data are
offered: Bridgman obtained for Pb- R100/R 30 = 0.694, for 5n;
R100/R 30 =0.707, for Cd-, RIOO/R 30 ~ 0.795. Under the same conditions

couparison with the width of line 2.11 recorded in the Ni-K,( radiations It was
observed that the application of pressure and heat led to an increase of the Microw,
hardness from 1800 to 3200 kglm' and to a substantial broadening of the diffrac-
tion lines. After annealing, these properties returned nearly to those of the
standard specimens. The change in the properties of the simLltaneously compressed

ABSTRACT: To explain the decrease of the resistance of p-type ger
manium with increasing pressure, whereas the resistance of n-type
germanium Increases, "the authors investigated the temperature de-
pendence of the resistance of p-type germanium at pressures up to
90 kbar, and at temperatures rang!mg from room temperature to 152C 0,
The beat was produced by a current-carrying,coil and the temperature'Z__

was measured with a thermocouple. The measurements have shown that
in p7type germanium the impurity conductivity predominates at room,
temperature throughout the investigated range of pressures. At roomt.'::.~.
I temperature the characteristic maximum at 40 kbar is observed. A
maximum is observed at higher temperatures when the intrinsicoonduc-
tivity begins to play the dominant role. The different pressure
dependence cf the two types of germanium is attributed primarily to I
the unequal ratio of the intrinsic and impurity conductivity, which
depends on the pressure, temperature,.and on the number of types of 11
impurities. -The width,of the forbidden gap is obtained at tempera- J;~
tures from 127 to 152C, being equal to the slope of the plots of the-1
logarithm of the resistance against the temperature. A plot of the
gap against the pressure is presented and is seen also to have a
maximum at 40 kbar. The plot of the gap is somewhat lower for p-type':~-'-
germanium than that obtained earlier (FTT v. 7, 1441 1965) for n-type
germanium, but the difference Is attributed to the difference in the
temperature intervals within which the -gap was measured. The autbors"-...~.

ABSTRACT: Firsto the effects of high oxygen pressures on the vital
activities of bean (vicia faba) and pea (Pisum sativum) sprouts were
determined in a special chamber with oxygen pressures ranging from-
I to 50 atm. Results showed that high oxygen pressures up to 50 atm
do not affect the growth of bean and pea roots,, Then tho effects of
high o.-."ygon pressures (1 to 50 atm) were investigated during X-irradi-
ation (RUM-11 unit, 185 kv, 13 ma, 45 r/min) with single 90 r doses
for 3 day old bean sprouts and 150 and 200 r doses for pea sprouts.
Findings showed that the radliation damage for bean sprouts continued

:to increase up to a certain level (30 atm) with increased oxygen
pressures and higher pressures protected the bean sprouts from
,penetrating radiation. Radiation damage for pea sprouts (150 r) was
.highest with oxygen pressure of 1 atm, and higher pressures protected
the surouts from radiation. Radiation damage for Dea sprouts irradia-
ted with 200 r was highest at oxygen pressures of i to 3 atm and
.pressures below 1 atm and over 3 atm. were radioprotective, The find-
ings on radiosensitivity change in relation to oxygen pressure during
radiation may be explained in terms of oxidation chain reactions with
,branching of chains. The anorialous dependence of the reaction rate
-on oxygen prossure appears to be based on certain oxygen pressure
conditions in which reactions do not take place, and which_ are Imourn
as the upper and lower oxygen pressure limits. Decrease or increase
of oxygen pressures beyond these limits at time of radiation protects
the Dlant from radiation damage and this position is supported by
literature data. Orig. art. has: 3 figures and 3 tables.
