ABSTRACT: This article deals with the application of numerical techniques, based
on the use of computers, to the solution of the direct problem of supersonic flow
past blunt bodies by the method of integral relations. The problem consists of
determining the single-valued and continuous solution for the region of minimum
effect of bluntness with boundaries formadby the shock wave AB3, axis of symmetry
AE, boar contour DE, and boundary characteristic B3D (see Fig. l). Three different
schemes of the method of integral relations are outlined for which the construction
of three algorithms are presented. The first one was constructed according to
scheme I for supersonic flows past axieymmetric bodies with equilibrium dissociation

gas ,flows past blunt bodies, with nonequilibrium dissociation taken into account.
The� third vas constructed by using double approximation according to scheme II, then
integrating and .approximating according to scheme I. It is said that due to the
difficulties in obtaining analytical evaluations of the accuragr and convergence
of the aethod of integral relations, the basic criterion should be numerical evaluation.'
To this end, calculations in various approximations were Carried out according to ea /
of tine three schemes for a sphere at M ~ 10~. The results are presented in tabular
form. For oo~arison, the values of gasdynamie parameters oP flaws calculated by
schemes Y and II are presented instable. The comparison shows good agreement,
althou~ an approximate representation oP tihe functions was used in opposite direc-
tions in each of the schemes. Orig. art. has: 5 figures, 11 Formulas, and 5 tables.

Title Horseshoe-shaped vortex during unsteady motion
Periodical Prikl. mat. i mekh., Vol. 19, 159-164, Mar-Apr 1855
Abstract : The author investigates the field of velocities which form in as ideal in-
compres~ible fluid from as associated vortex of finite span, whose intensity
gamma varies with time, and from the corresponding system of free vortices.
It is assumed here that the velocity of washing away of the free vortices
is constant in ~magaitude sad direction. For the case of constant gamma he
obtains the well known system of horseshoe-shaped vortices. For intensity
of the associated vortex that depends upon time, the free vortices fall off
from it; the axis are parallel to the axis of the associated. Moreover,
the intensity oi' each of the two free vortical strings parallel to the
velocity of washing away is less both along the length of the string sad
also is time. The results of the author's work pera~it oaa to pus over to
the solution oP the problem of the spatial aonstationary motion of an arbi-
trary weakly cambered supporting surface. dne reference: D. E. Lebrian,

Tn the aluminizir~~ of llrmco iron ~n pure aluminum, thcA daf2'usior~
layer consisted of two xone$s a thick none of colu~.r,ar cryptallitarrr oc~~oin-
ing tho iron, and, considerably thicIcer. a fine crystalline zone (2-3
+r~icrons} adjoining the aluminum, The columnar crystallites grew prec~gmi=
~ nantly in a direction perpendicular to the front of the reactive diffusion
(toward the specimen surface} with the formation of characteristic protu~
i ~-ions -- tongues.
rormation of the two-phase layer is the result of reactive diffusion
in the solid iron -aluminum melt systems the diffusion of aluminum atoms
promotes thQ growth of columnar crystallites and the overall thickness of
the layer, and in the straightfonrard diffusion of iron, atoms change in
t~.a condition of equilibrium of the system which leads to a decrease in
layer thickness. k'rom the thermodynamic point of view, this phenooeaon
boils down to an incroasa in antrapy of displacement and decrease in the
free energy of the system and, therefore, proceeds spontaneously and irre-
ve: 8~bly,
The result$ of microstructural and chemical analyses were confirmed
by roentgenographic investigation. Orig. art. has: 3 figures. LJPRS: 3b,,F~]

Similar to that of the central part of the diagram and degenerating
after longer annealing (on the order of six days), At a ca^iposition
rat~.o close to 1:1, the conductivity of the equilibrium alloy reach-
es amaximum while the thermal emf reaches a ~sinia, this being a
charact�ristic attribute of semiconductor solid solutions. A study
of the effect of impurities on the variation of the propertied of
the ternary alloy CdZn8b2 has shown that the elements of the fourth
period of th� periodic table (Cu, Se) increases the conductivity
to a maximum degree when the in~urity content is 1--296, whereas ele-
ments of the fifth period (Ag, Te) sharply increase the conductivity
even at a concentration on the order of 0.116. The influence of the
impurity is determined by the electron shell structure of the intro-
duced impurity. 8ibliogzaphy, 7 titl��. fit. 8h.
