Исследование влияния углов наклона и расположения отверстий на эффективность работы перфорационного охлаждения стенок жаровой трубы

Abstract

In this paper, a study was conducted on the influence of various geometric parameters of perforation cooling holes of a modern annular compressor station on the efficiency of the cooling system. The efficiency analysis was performed using CFD. The following geometric parameters of the cooling system holes were changed: angles of inclination of the holes; angles of rotation of the holes; types of hole geometry; the order of the holes (linear and staggered). The efficiency parameter was taken to be the value η, which is defined as the ratio of the difference in the temperature of the hot air at the inlet and the adiabatic wall temperature to the difference between the temperatures of the hot and cold air.
