The Study of Hybrid Method in the Onset of Droplet Escaping From the Film
説明
<jats:p>A particle-grid hybrid method for simulating the onset of droplet entrainment is described. The air and liquid phases are expressed by grid and particle separately. The effects of surface tension and wall adhesion are calculated by the continuum surface force model. The fluid film variation and the droplet disengaging procedure are analyzed. The onset of entrainment criterion is obtained and it has a good agreement with Ishii’s correlation. The influences of surface tension and gas phase density on the criterion are also studied. Several simulation flow fields are given for illustrating the efficiency of the method.</jats:p>
