Abstract
Prediction and evaluation of boiling phenomena are important for engineering field. In order to analyze boiling phenomena numerically, we have developed a computational method which is based on FVM discretization and CIVA interpolation method for treating complicated engineering problems. As for phase change model, we adopt the modified temperature recovering method. A comparison of the numerical results of hydrogen boiling problem shows good agreement with the past study by Juric et al.. Furthermore, for improving treatment of small bubbles whose size is less than the mesh resolution, we introduced a kind of two-phase model, two-velocity field model, for gas and liquid phase.
