Phase change heat storage in an enclosure with vertical pipe in the center | Mathematics

See on Scoop.itMicro generation – Energy & Power systems
This paper documents the fundamentals of heat storage bymelting a phase-change material inside a cylindrical enclosure with a vertical heated pipe onits axis. The phenomenon is studiedanalytically and numerically. The analysis consists of the scale analysis of the early stages of natural convectioninthe liquid, and an analysis of the entire duration of the melting process. The numerical simulations cover the entire process,and validate all the features predicted by theory.
