Abstract

In this paper, the implementation of the finite difference WENO scheme maintaining velocity, pressure and temperature equilibrium in the multicomponent compressible fluid analysis is discussed. First, the new finite difference WENO scheme is proposed for the quasi-conservative form which is often used in the finite volume formulation in the previous study. This new WENO scheme adopts the split form which separates the consistent and dissipation parts, and the dissipation part is formulated in a conservative form, keeping the conservation for conservative variables. The proposed scheme can keep the velocity, pressure and temperature equilibriums for the various problems. Based on the results here and previous studies, the vector form of numerical dissipation is reconsidered.
