Аннотация

Experiments are conducted to determine local heat transfer characteristics for jet array impingement cooling with initial crossflow. The results obtained from experiments show that: 1. The action of initial crossflow is similar to that of reducing z/ d; 2. The relative cooling effectiveness with initial crossflow in linine arrangement is better than that in staggered arrangement, and the difference becomes larger in the downstream region; 3. Under the action of initial crossflow, the relative cooling effectiveness undergos a variation from increasing to decreasing along the streamwise direction with change of z/d from 1 to 3.
