ABSTRACT

Characteristic results of experimental studies of heat transfer in separating flows behind single obstacles (in rectangular trenches, behind a back-step and a single fin with a wide range of geometric dimensions) are analyzed. Applicability limits of some laws of mean heat transfer are presented. A substantial degree of the influence of an external level of a turbulent flow past a fin and a step of various heights on heat transfer and coefficients of pressure in separation and relaxation zones is revealed. Intensification of a maximum coefficient of heat transfer by 15−20% is obtained for both obstacles.
