Follow-up proposal: Numerical investigations of compressibleturbulent boundary layers with pressure gradients and heat transfer

在这个后续项目中，将首次系统地了解可压缩湍流边界层中压力梯度和强换热的综合影响。为此，直接数值模拟的数据将在高性能计算机系统上计算和分析具有或不具有压力梯度和强传热的自相似可压缩湍流边界层，从而产生不受可能不适当的湍流模型影响的有洞察力的数据。因此，该建议是对先前建议的直接扩展，该建议侧重于具有压力梯度和轻度传热的可压缩湍流边界层。除其他外，这项研究将使我们能够验证（强）雷诺兹类比推导中所做的主要假设的有效性，已知这些假设仅部分适用于强传热情况，而不适用于具有压力梯度的湍流边界层。因此，这项工作的结果大大有助于我们对可压缩湍流边界层在复杂和现实流动环境中的主要行为的基本理解。

In this follow-up project, a systematic understanding of the combined influences of pressure gradient and strong heat transfer in compressible turbulent boundary layers should be gained for the first time. To this end, data from Direct Numerical Simulations will be computed and analyzed for self-similar compressible turbulent boundary layers with and without pressure gradients and strong heat transfer on a high performance computer system, yielding insightful data that are not affected by a potentially inappropriate turbulence model. Thus, this proposal is a direct extension of the previous proposal, which focused on compressible turbulent boundary layers with pressure gradients and mild heat transfer. Among other things, this study will allow us to verify the validity of the main assumptions made in the derivation of the (strong) Reynolds analogy, which are known to be only partially valid for cases with strong heat transfer and not for turbulent boundary layers with pressure gradients. The result of this work thus significantly contributes to our fundamental understanding of how a compressible turbulent boundary layer is expected to principally behave in complex and thus realistic flow environments.
