Comparative study of two corrective gradient models in the simulation of multiphase flows using moving particle semi‐implicit method

摘要

Summary >In this study, two corrective gradient models (CGMs) are compared in the simulation of multiphase flows. Linear consistency of the gradient model of moving particle semi‐implicit (MPS) method has been recovered by introducing corrective matrix. However, it is found that particles tend to disperse along the streamline while using the CGM proposed in a previous study. Particle shifting (PS) schemes are necessary to reduce the irregularity of particle distribution to stabilize the calculation. To enhance the accuracy and stability, another CGM with dummy particle (CGMD) was proposed in our previous study. This enhanced CGM is featured by linear consistency and purely repulsive pressure gradient force. In this study, this enhanced CGM is modified and applied to multiphase flow simulation. Comparative study suggests that the modified CGM with PS scheme is capable of calculating various multiphase flows and predicting the interface evolution both clearly and accurately. </abstract>

在本研究中，在多相流的模拟中比较了两个校正梯度模型（CGMS）。通过引入校正矩阵恢复了移动粒子半隐式（MPS）方法的梯度模型的线性稠度。然而，发现颗粒倾向于沿着流线线分散，同时使用先前研究中提出的CGM。颗粒移位（PS）方案是降低颗粒分布的不规则性以稳定计算的必要条件。为了提高准确性和稳定性，在我们以前的研究中提出了具有虚拟颗粒（CGMD）的另一种CGM。这种增强的CGM通过线性一致性和纯粹的排斥压力梯度力。在该研究中，这种增强的CGM被修改并应用于多相流动模拟。比较研究表明，具有PS方案的改进的CGM能够计算各种多相流并清晰准确地预测界面演变。</
