摘要/Abstract

摘要： 采用VOSET方法捕捉液液两相运动界面，对高密度差体系中单液滴的运动进行数值模拟，分析不同时刻的表面图和流线图及瞬态速度变化图，研究了单液滴运动过程的速度变化及形变。研究结果表明：液滴形变随密度差和液滴粒径以及界面张力减小而变得剧烈；液滴上升速度随密度差和界面张力的增大而增大；液滴速度振荡幅度随粒径减小而减小；液滴形变的频率随界面张力增大或粒径减小而变小。

关键词: 单液滴, 高密度差, 界面, 萃取, 数值模拟

Abstract: In this paper,the VOSET model was used to capture the moving interface of liquid-liquid two-phase flow,and the single droplet motion in the high density difference system was numerically simulated,and the velocity variation and deformation of single droplet were studied by analyzing the surface map,streamlines and velocity at different time.The research results indicated that droplet deformation would become more remarkable with the increase of density difference or droplet size.As density difference and surface tension force increases,the droplet velocity increases.The smaller droplet is,the smaller velocity oscillation amplitude is.

Key words: single droplet, high density difference, interface, extaction, numerical simulation
