摘要
采用Ansys Fluent 17.0对管道模型进行气液两相流数值分析,采用Euler模型计算出液相比例在5%、10%、15%时,对应液态颗粒直径分别为0.01mm、0.04mm、0.08mm时,管道内中轴面处静压流场分布和气液两相分布情况。模拟结果表明:增大液相浓度和液相颗粒直径都会导致压力损失,湍流增强,但增大颗粒直径的影响明显大于增大液相浓度。
This paper uses Ansys Fluent 17.0 to numerically analyze the gas-liquidtwo-phase flow of the pipeline model.Using the Euler model,when the liquid phase ratio is 5%,10%and 15%,and the corresponding liquid particle diameter is 0.01 mm,0.04 mm and 0.08 mm respectively,the static pressure flow field distribution and the gas-liquid two-phase distribution at the central axial surface of the pipeline are calculated.The simulation results show that increasing the liquid phase concentration and liquid particle diameter will cause pressure loss and turbulence enhancement,but the effect of increasing particle diameter is obvious greater than increasing the liquid phase concentration.
