水平布置等径气泡上升运动数值模拟分析
Analysis of numerical simulation on horizontal arrangement equal bubbles rising
摘要
Abstract
Numerical simulation of the bubbles’ rising was analyzed with the method of FTM (Front Tracking Method) by selecting the tiny bubbles as the objects in Fortran language .The influences of bubbles’ deformation on their movement were ignored .After contrasting and analyzing the changes of the flow field and velocity of one to four bubbles ,the results showed that the interaction between the bubbles was mainly influenced by the changes of the flow field .The terminal velocity of double bubbles was lower than the single one on account of the vortex counteracting of former and wake merging effects .However ,when three or four bubbles were moving upward ,the central one would surpass the bilateral bubbles and behave like the single and double bubbles .But they took longer time to achieve the ultimate velocity accordingly .关键词
