How to prevent pressure oscillations in multicomponent flow calculations: A quasi conservative approach. (English) Zbl 0847.76060
Summary: A new numerical scheme for computing multicomponent flows is presented. It is able to handle strong shocks, is pressure oscillation free through the contact discontinuities, and guarantees the positivity of mass fractions. Some numerical experiments on shock tubes indicate the convergence to the correct weak solution. Comparisons with classical finite volume schemes are also proposed.
