Modelling of heat transfer in combustion-chamber boundary layers (C06)

目的是研究实际气体物理和湍流冷却膜内的化学反应对跨临界和超临界操作条件下壁面热流的影响。研究了实气对实气冷却膜稳定性和效率的影响。在反应冷却膜的研究中，湍流的影响、详细的化学反应以及化学-湍流在冷却壁附近的相互作用是研究的重点。火焰与冷却壁面的相互作用，包括粗糙度效应和物质重组将被研究。目的是建立一个近壁传热模型在反应冷却膜在完整的火箭燃烧室配置的数值模拟。

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.
