A Kinetic Scheme Based On Positivity Preservation For Multi-component Euler Equations
Shashi Shekhar Roy, S. V. Raghurama Rao
A kinetic model with flexible velocities is presented for solving the multi-component Euler equations. The model employs a two-velocity formulation in 1D and a three-velocity formu…

A Kinetic Scheme based on Positivity Preservation with Exact Shock Capture
Shashi Shekhar Roy, S. V. Raghurama Rao
In this paper, we present a kinetic model with flexible velocities that satisfy positivity preservation conditions for the Euler equations. Our 1D kinetic model consists of two vel…

A kinetic scheme with variable velocities and relative entropy
Shashi Shekhar Roy, S. V. Raghurama Rao
A new kinetic model is proposed where the equilibrium distribution with bounded support has a range of velocities about two average velocities in 1D. In 2D, the equilibrium distrib…
