A novel hybrid approach for accurate simulation of compressible multi-component flows across all-Mach number
Xi Deng, Bin Xie, Omar K. Matar +1
Numerical simulation of multi-component flow systems characterized by the simultaneous presence of pressure-velocity coupling and pressure-density coupling dominated regions remain…

Positivity-preserving hybrid DG/FV method for compressible Euler equations with stiff source terms
Zhen-Hua Jiang, Xi Deng, Lin-Tao Huang +3
In numerical simulations of complex fluid dynamical problems, unphysical negative density or pressure may appear, causing blow-up of the computation. With the aim of obtaining posi…

On the convection boundedness of numerical schemes across discontinuities
Xi Deng, Zhen-hua Jiang, Omar K. Matar +1
This short note introduces a novel diagnostic tool for evaluating the convection boundedness properties of numerical schemes across discontinuities. The proposed method is based on…
