• Abstract

Heat transfer mechanism of phase change phenomena of vapor liquid in fluid through closing unit was simulated by condensation process with high level pressure .This model was simulated with two values of velocity of vapor phase and liquid phase through this process .This model designed by using a hyperbolic equation to predict the spatial and temporal temperature distribution of phase change phenomena in three dimensions depending upon pressure measurement values through different points in domain of condenser using FTCS method in numerical analysis of this model in simulation the temperature distribution in three domain of condense by using FTCS method. In simulation interface moving boundary condition was used to simulate the phase change temperature distribution in three dimensions at interface line saturation temperature. Experimental included design rig and measurement different parameters by using different instruments with high accuracy to verify the theoretical work with time dependent .These measurements were taken after time on hour of working the unit to give more stability and ideal work of phase change phenomena through condensation process.
