Abstract: The research presented in this paper is devoted to exploring the influence of up-stream periodic wake on the film cooling effectiveness on a downstream plate. This investigation is carried out through rigorous numerical simulations utilizing a ded-icated simulation model. The model was developed to examine the impact of up-stream periodic wake on film cooling performance across varying blowing ratios (M = 0.3, 0.5, and 1.0) and wake sweeping frequencies (10 Hz, 20 Hz, and 40 Hz). Comparative analyses are conducted with a baseline scenario involving a constant jet without wake. The objective of these analyses is to provide a deeper understand-ing of the mechanisms through which upstream wake influences film cooling per-formance, ultimately shedding light on the flow characteristics and cooling effec-tiveness of film cooling under sweeping wakes.
