摘要
采用移动粒子半隐式(MPS)方法分别对加热面水平、竖直和45°倾斜放置时流动泡核沸腾中1个汽泡的成长至脱离过程进行了二维数值模拟,并将数值模拟结果与实验结果进行了对比。结果表明:汽泡的形状与成长速率的数值模拟结果与实验结果相符合,数值模拟成功地预测了实验中观察到的汽泡脱离前的滑移现象。
In the present study,a two-dimensional numerical simulation of single bubble growth and departure during nucleate flow boiling was performed on the horizontal,45° inclined and vertical surfaces,respectively,using the moving particle semi-implicit（MPS） method.The numerical results are provided for bubble shape and growth rate,which show a good agreement with the data from the experiment.Bubble sliding motion prior to liftoff as observed in experiments was well predicted from numerical simulation.
