ABSTRACT In this paper, a new particle-grid hybrid method is used for numerical simulations of the gas-liquid two phase flow. In this method, the main area of the fluid is calculated via the constrained interpolated profile/multi-moment method (CIP/MM FVM), and the interface of the two phases is calculated by the finite volume particle method (FVP). In the numerical calculation, the particles are distributed in the dense one of the two phases, and only near the interface. Through calculations of the dam break, single bubble rise and bubble coalescence, the reliability and accuracy of the method in multiphase flow simulation have been verified.

粒子网格混合法在多相流计算中的应用

摘要 在本文中，一种新的粒子网格混合方法用于气液两相流的数值模拟。在该方法中，流体的主要面积通过约束插值剖面/多矩法（CIP/MM FVM）计算，两相界面通过有限体积粒子法（FVP）计算。在数值计算中，粒子分布在两相中较密的一相中，且仅在界面附近。通过对溃坝、单气泡上升和气泡合并的计算，验证了该方法在多相流模拟中的可靠性和准确性。
