Optimizing Solidification Process in Phase Change Energy Storage Units with Sinusoidal Wave-shaped Fins

Abstract Phase change energy storage units have attracted considerable interest in the field of technology. To overcome challenge low thermal conductivity associated with phase material (PCM) employed these units, researchers implemented fins various shapes. In this study, a two-dimensional numerical model unit newly designed sinusoidal wave-shaped is developed. The analysis done using commercial software ANSYS-Fluent transient state. solidification process PCM evaluated enthalpy–porosity method. validation against an experimental result from published article. study focused on increasing surface area fins, achieved by its crests and troughs counts, to analyse impact PCM. performances are quantitatively analysing solidified portion PCM, temperature distribution, rate heat release, velocity variation. shows that total time predicted for straight fin 115.34 minutes. This duration reduces it even further as counts increases. maximum reduction observed 19.93% 10 counts. It also initially decreases then marginally increases increase or effect buoyancy flow analysed at different locations within unit. movement near crest trough decreases.
