The research concerns a cornerstone of high-speed aerodynamics - unsteady SBLI behaviour at low Reynolds number conditions - and is relevant to applications including transonic aircraft, hypersonic spaceplanes, and Martian entry vehicles. The study will develop and apply state-of-the-art experimental facilities (Hiralal Patel Supersonic Wind Tunnel) and computational tools (PyFR). The development of these complementary capabilities (both of which are unique to Imperial) will generate detailed datasets and facilitate future studies that avoid the historical mismatch between experimental and low-fidelity (RANS) computational approaches to SBLI research and shed new light on the nature of unsteady SBLI at low Reynolds number.

该研究涉及高速空气动力学的基石-低雷诺数条件下的非定常SBLI行为-并且与包括跨音速飞机，高超音速航天飞机和火星进入飞行器在内的应用有关。该研究将开发和应用最先进的实验设施（Hiralal Patel超音速风洞）和计算工具（PyFR）。这些互补能力的发展（两者都是帝国独有的）将生成详细的数据集，并促进未来的研究，避免实验和低保真度（RANS）计算方法SBLI研究之间的历史不匹配，并揭示了在低雷诺数下非定常SBLI的性质。
