We present a γ‐model BGK scheme for the numerical simulation of compressible multifluids. The scheme is based on the incorporation of a conservative γ‐model scheme given in ( J. Comput. Phys . 1996; 125 :150–160) into the gas kinetic BGK scheme ( J. Comput. Phys . 1993; 109 :53–66, J. Comput. Phys . 1994; 114 :9–17), and is simple to implement. Several numerical examples presented in this paper validate the scheme in the application of compressible multimaterial flows. Copyright © 2004 John Wiley & Sons, Ltd.
