High resolution compressible CFD simulations High Resolution Compressible CFD Simulations First and second order numerical schemes are highly dissipative, thus leading to incorrect prediction of turbulent shock-wave turbulent-boundary layer interaction (SWBLI) induced separation. High-order (HO) schemes in conjunction with large eddy simulations lead to significantly better results, however, pressure fluctuations can be under-, or over-predicted, due to numerical dispersion errors. In the last few years, however, significant progress has been made with regards to the application of high-resolution (HR) and HO methods to compressible flows featuring acoustic excitation, turbulent SWBLI, and low-Mach number effects [1-3]. The aim of this project is to apply HR and HO methods to supersonic/hypersonic turbulent SWBLI and supersonic/hypersonic boundary layers inducing acoustic loading on the structure, and investigate both the accuracy and efficiency of these methods in the framework of advanced CFD methods, such as implicit large eddy simulation (ILES) and hybrid ILES/Reynolds-Averaged-Navier-Stokes (RANS).
