Influence of Mushy Zone Constant on Thermohydraulics of a PCM

The mushy zone constant is varied from 103 to 108, and its influence on the melt fraction and the amount of heat stored has been studied. Results are presented in terms of melt fraction and stream function contours, melt fraction and heat stored. Based on the study, it is observed that the mushy zone constant significantly influence the thermohydraulics of a PCM.
