Based on the internal cooling turbine blade of high-performance aeroengine
the internal heat transfer characteristics of double-plate configuration with film cooling have been carried out in rotating state.The test was performed in the same and opposite direction of rotation.Thus
the effect of jet Reynolds numbers Rej(5 000~10 000)
rotation numbers Ro(0~0.003 532)and wall-to-jet temperature difference ratios(Tw-Tf)/Tw(0.061~0.136)on heat transfer characteristics of impingement was obtained.By comparing the experiment results of both double-plate configuration and general configuration of impingement/effusion structure
it is observed that the heat transfer of double-plate configuration is 15% stronger than that of general configuration.
