... facilities by 150%. A strong dependence of the bow shock shape on cooling pressure was observed, but for the expected variations, the shock wave height changes by less than 1 mm. This low sensitivity ensures the proposed system remains robust to small perturbations in the effusion cooling conditions. Finally...

...Shoaib Ahmed; Benjamin H. Wahls; Srinath V. Ekkad; Hanjie Lee; Yin-Hsiang Ho One of the most effective ways to cool the combustor liner is through effusion cooling. Effusion cooling (also known as full-coverage effusion cooling) involves uniformly spaced holes distributed throughout the combustor...

... of this study. The contoured endwall was subjected to engine-representative combustor cooling flows and film cooling flows injected through a staggered row of discrete holes upstream of the passage inlet. The combustor cooling flows are simulated through effusion cooling flows and a louver cooling row. The test...
