摘要

在流体界面行为中，马兰戈尼效应(Marangoni effect)引发的粒子逆流现象对工业多相流调控具有重要意义。本文基于 COMSOL 软件构建了包含粒子追踪的流体-粒子耦合模型，定量研究了粒子质量、流体温度、注入高度及表面张力梯度对逆流现象的协同影响机制。仿真结果表明:降低注入高度(H=0．01 m 时逆流强度较 H=1．01 m 提升 63%)、增加体相流体温度(90 ℃时逆流路径长度较 30 ℃增加42%)、减小粒子质量(粒径 1×10－4m 的粒子上升高度较 3×10－4m 提高 2．3 倍)以及增强表面张力梯度均可显著强化逆流效应。研究揭示了界面张力主导的逆流动力学机制，提出了通过调控注入参数优化逆流强度的定量策略，为工业界面流控提供了理论依据。

Abstract:

In industrial production，there are often a variety of liquids between the injection behavior，and in the fluid miscibility phenomenon，due to the fluid molecules at the interface out of the main body of the internal force situation is different，resulting in the interface at the interface of the fluid has a different fluid properties than the fluid inside．One of the most obvious phenomena is the Magorani effect，which is manifested by the fact that the particles at the interface of the fluid below will flow counter currently along the water flow in the process of the fluid injection above． Therefore，this paper is a parameterized simulation study of this phenomenon．Based on the COMSOL simulation software，different dimensions of the " upstream pollution phenomenon" are simulated，and the simulation model of particle and fluid is constructed to parameterize the four variables，namely，particle mass，fluid temperature，injection height，and surface tension，and to investigate the effects of different parameters on the particle counter current phenomenon．

Key words: Margolani effect particle counter current fluid interface flow injection behavior
