On the extension of the AUSM+ scheme to compressible two-fluid models

Abstract This paper describes the extension of the AUSM+ scheme to the four-equation isentropic and six-equation compressible two-fluid models for gas/liquid flow, using as equations of state the perfect gas law for the gas and either Tait’s law or the stiffened gas law for the liquid. Numerical results on well-known two-fluid air/water flow benchmark problems, from nearly incompressible flows to fully compressible flows, are presented and discussed.
