中文摘要：
本文通过数值模拟的方法计算并分析主流进口湍流度、冷却流进口高度和进口马赫数对超音速气膜冷却的影响。计算结果表明,主流进口湍流度对超音速气膜冷却有较大影响,增大主流进口湍流度会减弱超音速气膜冷却效率,同时还表明,增大冷却流进口高度以及进口马赫数,能减弱主流湍流度对超音速气膜冷却的影响。
英文摘要：
Numerical simulations are used to assess the effect of free-stream turbulence,coolant inlet height and Mach number on supersonic film cooling.The results indicate that increasing free-stream turbulence reduces the adiabatic film cooling effectiveness,while increasing coolant inlet height and Mach number weaken the effect of the free-stream turbulence.
