Numerical simulation for two-phase flows using hybrid scheme

摘要

The present paper is devoted to the computation of two-phase flows using two-fluid approach. Two difficulties arise for the model: one of the equations is written in non-conservative form; non-conservative terms exist in the momentum and energy equations. To deal with the aforementioned difficulties, the non-conservative volume fraction equation is discretized by WENO scheme, and the CWENO-type central-upwind scheme is applied to solve the mass, momentum and energy equations. Computational results are eventually provided and discussed.
