NOVEL ENGINEERING METHOD OF CALCULATION OF HEAT TRANSFER IN A LAMINAR-TURBULENT BOUNDARY LAYER

The authors have carried out investigations of results of systematic numerical solutions to equations of a twodimensional laminar-turbulent boundary layer on the surface of a hemisphere using the Cebeci–Smith algebraic turbulence model [1] modifi ed 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]
