The goal is to investigate the effects of real-gas physics and of chemical reactions within turbulent cooling films on the wall heat flux at trans- and supercritical operating conditions. The real-gas influence on the sta-bility and efficiency of real-gas cooling films will be studied. The effects of turbulence, detailed chemistry and chemistry-turbulence interaction near the cooled wall will be the focus in the study of reacting cooling films. The interaction of flames with cooled walls including roughness effects and species recombination will be investigated. The goal is to develop a model of near-wall heat transfer in reacting cooling films in numerical simulations of complete rocket combustor configurations.

我们的目标是调查真实的气体物理和湍流冷却膜内的化学反应对壁面热通量在跨和超临界操作条件的影响。研究了真实气体对冷却膜稳定性和冷却效率的影响。湍流效应、壁面附近的详细化学反应以及化学反应与湍流的相互作用将是反应冷却膜研究的重点。将研究火焰与冷却壁的相互作用，包括粗糙度效应和物种复合。目标是发展一个完整的火箭燃烧室构型数值模拟中反应冷却膜的近壁传热模型。
