CALCULATION OF A TURBULENT BOUNDARY LAYER FOR SUBSTANTIAL POSITIVE PRESSURE GRADIENTS,

Abstract

In this article is exponded a new method of calculation ofa turbulent boundary layer, which is based on the boundary laws of friction and heat transfer in the diffusion region of a gas flow. There are obtained values of critical parameters at point of abruption of a turbulent boundary layer and the influence of heat transfer and compressibility of the gas on these parameters is established. It is shown that the law of heat transfer in the practical region of variation of the criterion Re** weakly depends on the pressure gradient. There are proposed methods of calculation of friction and heat transfer, based on the solution of integral relationships of momenta and energy with the use of boundary laws of friction and heat transfer.
