SINOPSIS

This paper presents developed and tested algebraic models of turbulent viscosity and thermal conductivity coefficients. The models have been developed in the form of one formula valid across the whole boundary layer. The empirical coefficients and parameters for accounting the action of several physical factors being modified, the models are generalized to applications in the analysis of a large class of near-wall turbulent flows. The approximate analytical and numerical solutions of velocity and temperature distributions, skin-friction and heat transfer coefficients, that have been obtained with the models, are compared in the report with experimental and computed data of several authors.
