本文在VOSET界面捕捉方法的基础上对控制方程进行修正,使其能够计算带相变的两相流问题,然后用这种方法计算水平壁面上的膜态沸腾.模拟得到的平均Nu数与Klimenko的关联式的计算结果基本一致.计算结果表明,在较低的壁面过热度下,膜态沸腾呈现气泡状流动;在较高的壁面过热度下,膜态沸腾呈现气带状流动.
This paper presents a revision for VOSET,to make it applicable to two-phase flow with phase change.With this method,film boiling on horizontal surface is simulated.Nu number obtained by our simulation agrees well with Klimenko's correlation.The results show that in low heat flux,vapor departs from the wall in the form of bubbles,while in higher heat flux,vapor departs in shape of ribbon.
