ANALYSIS AND IMPLEMENTATION OF THE GAS-KINETIC BGK SCHEME FOR COMPUTATIONAL GAS DYNAMICS
gas evolution model gas-kinetic BGK schemes entropy condition gas-kinetic Lax±Wendroff ˉux
2015/7/1
Gas-kinetic schemes based on the BGK model are proposed as an alternative evolution model which can cure some of the limitations of current Riemann solvers. To analyse the schemes, simple advection eq...
Dynamics of unsaturated poroelastic solids at finite strain

2015/7/1
We derive the governing equations for the dynamic response of unsaturated poroelastic solids at finite strain. We obtain simplified governing equations from the complete coupled formulation by neglect...
We present a finite element model for the analysis of a mechanical phenomenon involving dynamic expulsion of fluids from a fully saturated porous solid matrix in the regime of large deformation. Momen...

Design of Numerical Schemes Gas Dynamics usion Upwind Biasing Limiters Accuracy Multigrid Convergence
2015/7/1
The theory of non-oscillatory scalar schemes is developed in this paper in terms of the local extremum diminishing (LED) principle that maxima should not increase and minima should not decrease. This ...
