摘要: 针对一维双流体模型,通过推导双流体模型的压力修正方程,及相含率修正方程,将原本应用于单相不可压流动的压力修正系列算法推广至双流体模型求解,提出双流体模型的压力修正算法.在离散过程中运用高阶有界格式,在保证二阶以上精度的基础上克服了由相含率分布的阶跃所造成的数值结果非物理震荡.与公开发表算例进行对比,验证求解的可靠性.

Abstract: Two-phase flow is studied numerically using a one-dimensional two-fluid equation system. A hyperbolic type of governing equation is applied. The segregated solution method is promoted and adopted. By establishing mass conservation based pressure correction, SIMPLE algorithm is extended to two-phase flow simulations. Numerical results for well-known two-fluid air/water flow benchmark problems are presented and discussed.

Key words: two-phase flow, two-fluid model, SIMPLE, numerical simulation
