Development of AUSM-Type Solver for Analysis of Ideal Magnetohydrodynamic Flows
AUSMPW+ and M-AUSMPW+ were modified to solve the equations of the ideal Magnetohydrodynamics(MHD). Discontinuity-sensing functions in AUSMPW+ and M-AUSMPW+ were newly defined for MHD equations. In order to obt...

Computation of Multiphase Mixture Flows using RoeM and AUSMPW + Schemes
RoeM [1] and AUSMPW+[2] schemes, originally developed for the robust and accurate simulation of single phase gas dynamics, are extended to the compressible gas-liquid two-phase flows. We adopted homogeneous eq...

Multi-dimensional Limiting Process for Two- and Three-dimensional Flow Physics Analyses
In this paper, we extend the idea of MLP to three-dimensional space and present the multi-dimensional limiting process for three-dimensional flow. The basic idea of the multi-dimensional limiting condition is ...

Uncertainty of Solution in Euler Equations and Numerical Instability
Numerical instability is studied based on numerics and mathematics. It is frequently observed in the region where velocity is zero. In that region, Euler equations have numerous solutions and, thus, it is impo...
