摘要：

The authors have carried out investigations of results of systematic numerical solutions to equations of a two-dimensional laminar-turbulent boundary layer on the surface of a hemisphere using the Cebeci-Smith algebraic turbulence model [1] modified in [2, 3]. From these investigations, the authors have proposed a novel engineering method of calculation of convective heat transfer; which is based on the use of approximation formulas to calculate the enhancement of convective heat transfer due to turbulent pulsations of the gas in the boundary layer. A comparison has been made of the calculated data corresponding to the employment of this method and analogous data obtained within the framework of formulas of considerable practical use from [4].
