Abstract : 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 guaranties the positivity of mass fractions. Some numerical experiments on shock tubes seems to indicate the convergence to the correct weak solution. Comparisons with classical finite volume schemes are also proposed.
