The behavior of bubbles and the process of coalescence are simulated by a computational multi-fluid dynamics (CMFD) simulation code TPFIT, which will contribute to develop the prediction method of critical heat flux based on the liquid-layer evaporation model. In this study, the calculation results in various pressure condition will be shown and the effect of the pressure on the behavior of bubbles will be discussed.
