• Fluid and thermal behaviors in gas and liquid phase in closed container were investigated by numerical calculation. In this calculation, mass and energy transfer due to evaporation on free surface was considered. Natural convection in both liquid and gas phase were separately calculated. In gas phase, binary diffusion convection including mixture of vapor component and non condensable gas were additionally considered. In these calculations thermal stratification was obtained in liquid phase by applying heat at side wall. Evaluation tests by using mixture of ethanol and nitrogen gas were also conducted. Pressure history was compared with calculated results, and it was proved that calculated results agreed with experimental ones.
