A second-order γ-model BGK scheme for multimaterial compressible flows

Abstract: We present a second-order γ-model BGK scheme for compressible multimaterial flows, which extends the authors' earlier work on a first-order scheme [7]. The scheme is based on the incorporation of a conservative γ-model scheme given in [1] into the gas kinetic BGK scheme [11,18]. Several numerical examples presented in this paper validate the scheme in numerical simulations of compressible multifluids.
