Abstract

The first order kinetic flux vector split scheme is found to be more dissipative, resulting in smearing of discontinuties. In this paper we have proposed a modified kfvs based on MCIR splitting with a molecular velocity dependent dissipation control function. Different choices for the dissipation control function and the corresponding physical arguments have been presented. The m-kfvs split fluxes are presented. The corresponding split flux Jacobians and the coefficient of numerical dissipation are studied. The scheme is tested on some standard test cases and the results are presented. The m-kfvs scheme is shown to be non-oscillatory at discontinuties and near second order accurate in smooth regions.
