摘要: 提出一种求解BN非守恒型两相流模型的方法.从微观角度出发,构造与BN模型相匹配的Gas-kineticscheme(GKS),通过对粒子速度分布函数积分求矩得到通量,把非守恒项直接包含到数值通量的演化和构造中,较好地处理了方程中包含的非守恒项.数值试验说明本方法的有效性.

Abstract: We propose a method for BN two-phase flow containing non-conservative terms. In microscopic aspect, a GKS model which matches with the BN model is constructed. Numerical fluxes are obtained with integrating particle velocity distribution function. And non-conservative terms are explicitly introduced into evolution and construction of numerical fluxes. Non-conservative terms are well handled. This method avoids complex iterative process of Riemann solver. It has high calculation efficiency. Numerical tests show high precision.

Key words: two-phase now, GKS, non-conservative, KFVS
