TEXT The kievskiy politekhnicheskiy institut (Kiev Polytechnic Institute) designed a test stand for studving
the turbulent boundary layer in order to find optimum methods for its control. The distribution of velocitv
in the jet cross-section and the turbulence spectra were investigated. Avcragc velocities and fluctuations %k ere
measured by meani of the '3TAM-3A (ETAM-3A) electric hot-wire anommeter designed by the VI-I
Width of the nozzle wire was 19 micr. The average flow velocities were found from the current intensity
of the measuring bridge, and the degree of turbulence, from the readings of a C-95 (S-95) electrostatic voltmeter
connected to the amplificr output. Shape and frequency of fluctuations as well as their relative amplitude
were determined by means of a -3114-7 (EI-7) cathode-ray oscilloscope and recorded on a M 110-2 1 M PO-2)
oscillograph. Calibration was done by a reference Prandtl-tube. A 500 c time marker was used for determining

element, fastened to the flume bottom and connected to piezoelectric weighing scales designed by the Institut
mckhaniki AN USSR (Imaitute of Mechanics, AS. UkrSSR) was used for determining the stresses oil the
surface. The scales had the following design features: during measurement the crystal-bearing ring driven by
a special gear induces in the crystal an alternating voltage. Due to this method, distortions of measurement
results, caused by leakage of the charge from the crystal, can be avoided. The accuracy of scale readings is

TITLk;t On the problem of aea-bre*ze circulation
PLRIODICALs Akademiya nauk Armyanskoy SSR. Izvestiya,
v. 15, no. 6, 1962, 61 - 74
TEXTt This paper is concerned with sea-breeze
circulation due to temperature non-uniformity of the under-
lying surface and which exhibits a diurnal variation. An attempt
is made to set up a model of this circulation within the frame-
work of a linear theory. The analysis starts with the general
equations of hydrothermal dynamics, i.e. the three equations of
motion and the equations of,continuity, state, and the inflou of
heat and humidity. Differential equations for the problem are
then established on the assumption that terms involving horizontal
mixing can be neglected, and the brpeze may be regarded as a small
perturbation of the general motion due to local non-uniformity in
the underlying surface. The final model takes the form of six linear

partial differential equations involving six unknown functions:
three velocity components, (U,V,W), pressure (p), departure of
the temperature from the steady state value (-0%), and humidity (q).
The boundary conditions are i
(1) Z - 500 U a V a W 0 0'.6 -'60 (x9y9t)' q - qo (x'Y't);
(2) when z--*co, u-v- p- 1~- q-0.
40 may be taken from observations, q0 is the humidity corres-
ponding to saturated vapor pressure at '~o for points above water
surfaces, or is obtained experimentally for other points. The
solution is sought in the form of a Fourier series and the coeffi-
cients of this series are evaluated approximately for each of the
above unknown functions. In the initial stages of the analysis
the solution is obtained for a constant turbulent mixing coefficient.
An outline is then given of how this restriction may be removed
and, in particular, the case is considered where the above coeffi-
cient is a linear function of height. The paper is entirely theore-
tical; an analysis of the various results and an account of numerical
calculations will be given in another pAper.

ilations under different conditions. These data were obtained by
:gradient observations during the wintertime, and used to plot the pro.
;files of the wind velocity in a layer of 12 meters over the water.
iThe experimental points are remarkably close to the th6oretical curvei
'based on a logarithmic law, in spite of the fact that the water-air
temperature fluctuates within + 5C, and sometimes even more. In the
!
lease of temperature difference-s exceeding 1010, the velocity profiles$
Plotted on a semilogarithmic scale, bend somewhat towards the ordinati
i
:axis, signifying that the additional development of turbulence due
ito thermal factors leads to a decrease in the vertical velocity
tgradient. Since this Is the oppouite of what takes care in the case
,of inversion, it is concluded that development of turbulence leads to
I
,equalization of the velocity profile of the wind. Orig. art. has:

ABS T iMCT: The author employs a method developed by S.M.Targ (Osnovnyyi zndachl teori
laminarny1di techenyy, Gostekhizdat, 1951) to calculate the two-dimensi)nal electro-
hydrodynamic flow in a plane exit cone. It Is believed that the resu'.ts may be of
assisLance in evaluating the possibilities of the electrohydrodynami.. technique for
influencing, the flow of liquid and gaseous dielectrics. Among the simplifying assump-4
tions employed in the calculations are the following: the vertex a-gle of the exit
cone is small; the electrical Reynolds number is small; the azimuthil component of the
electric current vanishes; the component of the radical electric c, rrent due to the
space charge field is small compared with that duo to the external radial electric
field; and the plane dielectric walls of the exit cone are neither charged nor polar-
ized. The flowing medium is assumed to carry a space charge. 7%e slectrohydro-

dynamic equations of motion are derived under these assumptions with barodiffunior
taken into account. These equations are linearized by the technique of Targ (lor
and approximate solutions of them are obtained. Formulas for the total pressure drop
and the position at which the flow breaks from the wall of the exit cone are given
in terms of the total flux and other parameters of the problem. Velocity profiles
are presented graphically for two specific cases. Orig. art. has: 44 fomulas and 3

TaT: The auti,ors report or', ir,vestli.,-aLif,~ns carrled out by a ;oviet
organization [Abstracter's note: No naime gven] to aeposit a silver coating of
1.0 - 1.5 mm, thckness on steel by the electrolytic method. The silver was
deposited directly on the steel and on a nIckel. sublayer. The specimens were
made of 30 XI'CA (30KhGSA) grade steel, and were pretreated in a solution con- -
taining 30 vol.% sulfuric acid (speci'ic pravfty 1.84), 3c, vo-,.% Qrtnophosphoric
ac.'d (specific gravity 1.57) and 40 vo,. % water. The specimens were pickled 2
for 5 - 6 minutes at 20 - 300C and an ano,lo ourrent density of 20 - 25 amP/tIm
After pickling and flushing in cold runn:r;g water the specimens were either
directly sil-ver-plated or, a sublayer, off' ril'ckel was applied from an electrolyte
containing (gram/liter): nickel sulfate 200, nickel cnIoride - 30, boric
acid - 30, a=jonium sulfate - 1.0, PH 3-') 4. After the nickel plating the
specimens were subjected to preliminw-y .9ilver plating In an electrolyte

30 - 40, potassium cyanide - 120 - 160, ;)otasslum carbonate - 40 - ,'-)0, caustic
potash - 1.2 - 2.0. The electrolyte temperature was 40 + 50C, the current
density 5 - 10 amp/dm2 and the currer,,, yle,Li 90 - 95%. 'Iring the electro-
deposition process the electrolyte was ,;t.rred continuously. A deposition of

not peel off. The adhesion stren6th of tn,_~ silver layer was also proved by
milling. The author gives a brief aescr' ';~~Ilon of the silver plating of a small
aluminum-alloy cylinder. There is I figure.
