A heat transfer model for phase-change thermal energy storage
MetadataShow full item record
The modeling of the heat-transfer process in a phase- change storage media consisting of parallel flow channels is presented. The model describing the mechanism of heat transfer from process air stream to the surface of phase- change material by convection and diffusion of heat in the media consists of coupled/ nonlinear partial differential equations. These equations are solved by a finite difference scheme. Numerical solutions were used to study the performance of phase-change storage media during a single blow operation. A parametric study is also carried out for different nondimensional parameters and operating conditions.
