TITLE The Heat Transfer under the Conditions of a Free Laminar Motion

In the present work the attempt is made to obtain a theoretical solution of the
problem of the free convection of a gas on a vertical wall in consideration of
the temperature-dependent variability of viscosity. The mathematical problem is
formulated by means of a system of dimensionless equations in which e- - 2- (T)
is the viscosity coefficient and Q - Q (T) denotes density. The problem is then
simplified by assuming heat transfer to take place only under the effect of a
free convection and on a wall of infinite length. A system of differential equa.
tions is obtained which is solved by the method of successive approximations.
The differential equations obtained can be transformed into such for an incom-
pressible liquid. The dependence obtained by MIHEEV for the case of a developed

TITLE The Influence Exercised by Free Convection on the Resistance
Coefficient of a Plate in the Case of a Laminar Behavior of the
Flow in the Boundary Layer.

Issued: 12 / 1957
The influence exercised by the forces of gravitation on the flow in a laminar
boundary layer has hitherto been but little studied. The present work makes
the attempt to solve this problem for the case of a compressible gas flowing
round a plane plate at low values of FROODIS criteria. - At first this prob-
lem is expressed by a system of dimensionless equations which are explicitly
written down. Next, a relation for the external flow round a plane plate is
obtained. The system of equations first mentioned is several times trans-
formed, after which the corresponding boundary conditions are written down. -
One of the (simplified) equations of the transformed system is solved by
using an approximated dependence for temperature by means of the operation
method. On this occasion a LAPLACE transformation is several times applied to
these equations. In order to-be able to use the tables of the incomplete
r -function a substitution of the variable is introduced. After some further
computations formulae for the resistance coefficient of the plate are obtained
as well as for the value of the resistance coefficient averaged over the length.
Finally, the numerical values of the coefficients are introduced into the
formulae.

After carrying out the corresponding computations the value 0-722 is obtained
for the average (apparently dimensionless) velocity. On the assumption that
this value 0,722 is not invariable in the case of low values of (Gr/Re2)coa a,
a formula for the computation of the relative resistance coefficient is then
derived. The accuracy of approximation is estimated and found to be satis-
factory.
For the relative resistance coefficient the following formula is found:
~f /Cf'(Gr/Re2)- 0. 1-0,498(Gr/Re2)coo a. (The significance of Gr is not men-
tioned and Re denotes REYNOLD'S criterion). If, for the limit of the in-
fluence exercised by the force of gravitation, the equation
af/d_f,(Gr/Re2) 1,05 is assumed, a dependence is obtained by satisfying
which it is possible to neglect the influence exercised by the forces of
gravitation on the summary resistance coefficient (Gr/Re2)008 a ~<
0, 1 . The
relative modification of the coefficient of heat transfer by the influence
of the forces of gravitation is not greater than the corresponding modifi-
cation of the resistance coefficient averaged over the length.
