Keywords:
convection; heat transfer; channel; mathematical model; straightening of border; convolution type functional; Euler equations; approximate solutions.Abstract
For linear problems of convective heat transfer processes with variable thermophysical characteristics of the medium, velocity of stream, volumetric heat generation sources, parameters of boundary conditions and crosssection of the channels the convolution type functional is obtained. Through its employment the approximate analytical solutions for determination of temperature fields in the stream is developed. An example is provided for its description in the flat and ring?shaped channels.Downloads
