气液两相流内气泡尺度升力效应的数值模拟
Numerical simulation of lift effects on bubble diameter in gas-liquid two-phase flow
摘要
Abstract
To investigate the influence of different interphase force models and bubble diameters on the numerical simulation of gas-liquid two-phase flow,a three-dimensional numerical approach based on the Euler-Euler two-fluid model was employed to simulate the two-phase flow in a bubble column.Under two distinct gas-liquid flow regimes in the column,the interaction between the lift force and bubble diameter and its effect on gas holdup distribution were analyzed in detail.The results show that when the lift force is neglected,bubble diameter has minimal impact on the numerical predictions.However,when the lift force is incorporated,the direct correla-tion between the lift coefficient in the Tomiyama model and bubble diameter leads to a negative lift coefficient for large bubbles(db>5.8 mm),driving them toward the center,and a positive lift coefficient for small bubbles(db<5.8 mm),pushing them toward the wall.This mechanism significantly influences the gas holdup distribution in the bubble column.The findings reveal the critical interaction between lift force and bubble diameter,providing important insights for improving the accuracy of gas-liquid two-phase flow simulations.关键词
