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…

Implementation of BVD (boundary variation diminishing) algorithm in simulations of compressible multiphase flows
Xi Deng, Satoshi Inaba, Bin Xie +2
We present in this work a new reconstruction scheme, so-called MUSCL-THINC-BVD scheme, to solve the five-equation model for interfacial two phase flows. This scheme employs the tra…
