Multiscale compressible turbulent flow is widely present in the aerospace field, and co-existence of shock wave discontinuities multi-scale turbulence field poses significant challenges for high-fidelity numerical simulation. To design high-order nonlinear scheme to improve accuracy complex simulation with stable capture, a weighted compact – targeted essentially non-oscillatory (WCNS-T) developed based on within WCNS framework. Also, an improved variant WCNS-T smooth scale separation...
Abstract Turbulent flow widely exists in the aerospace field, and it is still challenging to realise accurate prediction numerical simulation. To high-fidelity simulation of compressible turbulent flow, a high-order self-adaptive turbulence eddy (SATES) method developed on PHengLEI-HyOrder open-source solver, combining with weighted compact nonlinear schemes (WCNS). The subsonic transonic numerically simulated, including some typical cases, such as past circular cylinder square cylinder,...
