文摘

Dynamics of vapor bubble in uniformly superheated liquid is studied by a 3D LBM. The growth rate reaches a maximum value and then decrease until a certain value. The vapor bubble will take place a larger deformation at high ratio of Re/Eo. The bubble wake has a great influence on motion and deformation of vapor bubble. Ratio of Re/Eo has an important influence on evolution of temperature field.
