为了进一步阐明气膜冷却问题，本文给出了切向喷射槽下游湍流边界层的速度和温度分布。的配置文件主要是指一个注射质量的速度为0.36倍的自由流，这些和其他辅助结果表明一个复杂的流体动力学和相对简单的热行为，其中的温度分布似乎是在所有情况下是相似的。通过使用这种对应关系以及在大部分下游区域中充分发展的流体动力层的近似值，可以使先前提出的绝热壁温合理化。
Velocity and temperature profiles are presented for the turbulent boundary layer downstream of a tangential injection slot for the further clarification of the film-cooling problem. The profiles refer primarily to an injection mass velocity of 0.36 times that of the free stream; these and other auxiliary results demonstrate a complex hydrodynamic and relatively simple thermal behavior in which the temperature profiles appear to be similar in all cases. By using this correspondence together with the approximation of a fully developed hydrodynamic layer in most of the downstream region, it is possible to rationalize the adiabatic wall temperatures that have been presented previously.
