Blast Computation Using Harten's Total Variation Diminishing Scheme.

摘要

A model for blast field calculations involving two distinct gases is described. It is based upon the Euler equations and Harten's Total Variation Diminishing (TVD) scheme is used as the equation solver. The eigenvalues and eigenvectors are first derived for a general equation of state. Then a particular equation of state is presented for a mixture of two ideal gases. The model predictions show good agreement with experiment data for a shock diffraction around a corner.
