Numerical investigations on interactions between 2D/3D conical shock wave and axisymmetric boundary layer at Ma=2.2
Yihui Weng, Qin Li, Guozhuo Tan +2
Numerical simulation and analysis are carried out on interactions between a 2D/3D conical shock wave and an axisymmetric boundary layer with reference to the experiment by Kussoy e…
Quasi-linear analysis of dispersion relation preservation for nonlinear schemes
Fengyuan Xu, Pan Yan, Qin Li +1
In numerical simulations of complex flows with discontinuities, it is necessary to use nonlinear schemes. The spectrum of the scheme used have a significant impact on the resolutio…
Third-order scale-independent WENO-Z scheme achieving optimal order at critical points
Qin Li, Xiao Huang, Pan Yan +1
As we found previously, when critical points occur within grid intervals, the accuracy relations of smoothness indicators of WENO-JS would differ from that assuming critical points…
On developing piecewise rational mapping with fine regulation capability for WENO schemes
Qin Li, Pan Yan, Xiao Huang +2
On the idea of mapped WENO-JS scheme, properties of mapping methods are analyzed, uncertainties in mapping development are investigated, and new rational mappings are proposed. Bas…
Hybridizing WENO implementations of interpolation and reconstruction-wise operation for upwind-biased schemes with free-stream preservation
Qin Li, Dong Sun
Cases have shown that WENO schemes usually behave robustly on problems containing shocks with high pressure ratios when uniformed or smooth grids are present, while nonlinear schem…
WENO interpolation-based and upwind-biased schemes with free-stream preservation
Qin Li, Dong Sun
Based on the understandings regarding linear upwind schemes with flux splitting to achieve free-stream preservation (Q. Li, etc. Commun. Comput. Phys., 22 (2017) 64-94), a series o…
Interpretation of wake instability at slip line in rotating detonation
Pengxin Liu, Qin Li, Zhangfeng Huang +1
In studies on instabilities of flowfield in rotating detonation, one of the most common concerns is the instability at the slip line originating from the conjunction of the detonat…
Further investigations on the interface instability between fresh injections and burnt products in 2-D rotating detonation
Qin Li, Pengxin Liu, Hanxin Zhang
Instabilities in rotating detonation are concerned because of their potential influence on the stability of operation. Previous studies on instability of 2-D rotating detonation ma…
On free-stream preservation in stationary grids for arbitrary linear upwind schemes
Qin Li, Dong Sun, Hanxin Zhang
In order to improve the application maturity of high-order difference schemes, the free-stream preservation property, whose importance has been widely recognized in recent years, h…
