THE EXPERIMENTAL AND NUMERICAL RESEARCH OF INFLUENCE OF COOLING JETS POSITION ON TURBINE CASCADE PERFORMANCE

摘要：

With the increase of turbine inlet temperature, the technique of high efficiency film cooling to decrease the blade surface temperature has become a hot topic of turbine design. In this paper, a series of film cooled turbine cascade experiments are carried out and the influences of cooling jets position on turbine cascade performance are compared. A numerical code is used to simulate the effects of cooling jets position on cascade total loss. The flow field structure is analyzed through the numerical simulation. The numerical results show that the total performance parameters are approximately consistent with the experimental results.
