Yongzhi Luo, Huiheng Fan, Wei-Gang Zeng +2
This paper presents a family of high-resolution weighted essentially non-oscillatory compact least-squares schemes with implicit time integration for the compressible Navier-Stokes…
A general positivity-preserving algorithm for implicit high-order finite volume schemes solving the Euler and Navier-Stokes equations
Qian-Min Huang, Yu-Xin Ren, Qian Wang
This paper presents a general positivity-preserving algorithm for implicit high-order finite volume schemes solving Euler and Navier-Stokes equations. Previous positivity-preservin…
A fourth-order finite difference scheme with accurate dispersion and adaptive dissipation for computational aeroacoustics
Y. H. Li, Y. X. Ren, Y. T. Su
For computational acoustics, schemes need to have low-dispersion and low-dissipation properties in order to capture the amplitude and phase of the wave correctly. To improve the sp…
Instability and Mixing of Gas Interfaces Driven by Cylindrically Converging Shock Wave
Wei-Gang Zeng, Yu-Xin Ren, Jianhua Pan
In the present paper, an efficient method to generate "pure" cylindrically converging shock wave without a following contact surface is proposed firstly. Then, the Richtmyer-Meshko…
