ABSTRACTa A new waveguide method, developed by Le Bot and
Le Montagner (Ref 1), was used to measure the temperature
dependence of the complex permittiv:Lty of methyl and
ethyl alcohols between +50 and -60'*C, After a brief
recapitulation of the method and its advantages (Ref 2
to 5) the authors list their results, obtained at a
wavelength of 3-22 cm. in a tAble on p 137., Typical
results are given below

ABSTRACT: In a granular layer which is in a state of suspension
(dynamic equilibrium) in a stream of water, the following
phenomenon is observed: the speed of settling of the
solid particles forming the layer decreases with
increasing concentration and the particles themselves are
in a state of continuous chaotic motion or circulation.
The aim of the author was to investigate for low Reynolds
numbers of the particles certain problems of the nature
and the mechanism of this phenomenon, namely, what is the
regime and the structure of the water flow in the
suspended granular layer, what forces bring about a drop
in the speed of the "constrained" settling of the
particles in the layer and what is the relation between
Card 1/4 the circulation of the individual solid particles and

SOV/24-58-5-28/31
Investigation of the Constrained Settling of Solid Particles
in the Case of Low Reynolds Numbers
what is the influence of this circulation on the parameters
of the suspended layer and the water flow in it. The
experiments were carried out with wofatite (sulphated
resin) with average equivalent particle diameters of
0.17, 0.22, 0.29 and 0.37 mm. The layers consisting of
these grains were brought into the suspended state by a
stream of water with various speeds of flow inside a glass
tube of 37 mm dia., 1.5 m height; for each particle size
the expgriments were carried out at water temperatures of
4 to 22 C, whereby the Reynolds numbers of the particles
varied between 0.15 and 4.8. The circulation of particles
was studied in presence and in absence of particles in the
suspended layer; the second condition was complied with
in a layer having an upward motion and a constant
concentratio- and was achieved by feeding into the bottom
of the laye- a mixture of water and solid particles.
The thus obtaiaed experimental relations between the
volume concentration K of the solid particles and the
ratio of the speed of m8vement of the water above the
Card 2/4 layer Vo and the speed of the free precipitation of the

:30V/24-58-5-28/31
Investigation of the Constrained Settling of Solid Particles

particles V are graphed in Fig.l. It can be seen
that for an Rpward movement of the layer, the speed of
the constrained settling of the solid particles in the
case of absence of circulation of the solid particles is
higher than in the case of the layer bein,:,, under
conditions of dynamic equilibrium. Consequently, the
circulation of the particles produces an additional
resistance to their settling. In Fig.2 the oscillograms
are reproduced of the speeds measured at the heiGhlz of
400 and 8 mm. respectively above the layer and directly in
the layer; these show that in the layer and directly above
it the regime of water flow is turbulent, whilst at a
considerable distance from the layer it is laminary. It
is concluded that in the layer of the suspended grains,
speed pulsations and a turbulent regime of movement of
these components will occur due to frcquent and sharp
changes of the shape and the cross section of the local
components of the flow. These pulsations bring about
chanoes in the amount of motion between larver groups of
Card 3/4 molecules,which results in an increase of the apparent

viscosity and in an increase of the resistance to
settling of the particles. A relation is derived,
Eq.(15), which represents the relation between the
changes of a as a function of K (a = coefficient
taking into consideration the ratis of the real amount
of movement to that calculated from the avera,6e speed
and reflecting the non-uniformity of the speed
distribution along the live cross section of the flow).
This relation is compared with experimental data. For
certain values a full analogy is obtained between the
derived relation and the Einstein formula. The relations
derived in this paper can be applied in calculating.

TITLE: On Diffusion in a Fluidizei Bed (0 diffuzii v kipyashchem
sloye)
PERIODICAL: Inzhenerno-fizicheskiy zhurnal, 1959, Nr 4, PP 5-7 (USSR)
ABSTRAM An intensive circulation of solid particles and fluctuations
of their concentration occur in a fluidized bad. The cause of
circulation is pulsation of velocities and pressures in the
bed resulting from,the frequent and abrupt changes in the
cross section of the liquid flux circumfluent the solid
particles. The All-Union Scientific Research Institute of
Railroad Transport carried out experimental investigations of
this p4enumenon. A special device, described in the article,
was enloyed in which the'fluidi;Fed bed of granular material,
brought into a suspended state by the ascending water jet,
was created. The experiments have shown that solid particles
flow continuovely from the section in which the fluidized bed
was created into another section, if the aperture separating
them is opened. The motion of the particles proceeds in the
Card 1/3 absence of a positive gradient of hydrostatic pressure. It

I

is assumed that this motion occurs due to the presence of a
concentration gradient and a difference in hydrodynamical
parameters of the media in the fluidized bed and beyond its
borders. Thus it represents a phenomenon of diffusion. It,
was established that the velocity of the motion of particles
from the fluidized bed does not depend on their geometrical
dimensions, the height of the bed and on the water tempera-
ture, but is determined by two parameterst the volume con-
centration of the particles and their density. The results
of the experiments are represented in graphical form and
show that the diffusion rate of the solid particles rises
with an increase in their density and concentration up to
a certain maximum and then falls down to zero at Ko (volume
-oncentration) when'the bed goes over from the fluidized
state into-a stationary one. A certain similarity between
diffusion and hydraulic resistance in the fluidized bed was
found which resembles the similarity of these quantities in
turbulent transfer. The appurent viscosity and apparent
density of the two-phase mixture are higher than those of a
free single-phase flow. The author assumes that the appa-
.rent density -of the two-phase mixture in the fluidized bed

tions and pulsations of velocities, which is analogous to Ein-
stein - Smoluchowski's hypothesis on fluctuations in the densi-
ty of a viscous liquid.

TITLE. The unsteady evaporation of a liquid drop covered with an adsorption layer
,SOURCE: AN SSSR, Doklady*, v. 155, no. 3, 1964, 644-646
TOPIC TAGS: monolayer, macroscopic film, liquid molecule, molecular diffusion,
unsteady evaporation, drop evaporation, desorption, molecule transfer,
adsorption equilibrium
ABSTRACT: A previous error in the treatment of the unsteady evaporation of a
liquid drop through a monolayer led to an erroneous formula for the rate of non-
steady evaporation (B. V. Deryagin et al., DAN, 135, (1960) 1717~ and encouraged
this report on thv mentioned evaporation. Discussed in this connection is the
unsteady evaporation of a liquid drop with a radius.A covered with a monolayer of
foreign matter and stationary in relation to an infinite gas medium. The
assumption is made that the formation of an adsorption equilibrium is based on the
formation of an adsorpcive vapor layer on the surface of the moaolayer of foreign
matter. It is believed that the effect of the monolayer on evaporation may be the

result of the concentrati6n effectiveness of evaporarion reduced by a magnitude
proportional to the resulting flow of molecules through the monolayer. This
interperetatioa is somewhat analogous to:,Ohm's law. The proportionality factor
can be treated as t~e resistance of the jonolayer to evaporation. and the in-
complete "adhesion" of th~ vapor molecules to the monolayer can be attributed to
diffusion air resis~a

TITLEs The Influence of Monomolecular Layers Upon the Evaporation of
Drops
PERIODICALt Doklady Akademii nauk SSSR, 196o, voi. 135, No, 6,
pp. 1417 - 1420
TEXT: The authors develop a theory of the influence of monomolecular
layers upon the evaporation of drops, which takes two effects into
account: 1) the quasi-steady evaporation of a drop covered by an insoluble
film of a different substance, and 2) the nonsteady evaporation of a drop
covered by such a film. For 1) the following is taken into accounti a) the
steady diffusion of liquid molecules through the film, b) the steady
diffusion o,' liquid molecules from the film into the air. The following
relations are written for these processes: C 1 . A1/r + B 1; a< r< a + 6;
C2 . A 21r + B2 ; r> a + 6 +A-. C, denotes the number of liquid moleculcs
