Enhancement of Energy Recovery in a Phase Change Energy Storage Module with Embedded Radiation Absorbing Particles

 Abstract —The present study investigated combined enhancement of heat conduction and thermal radiation in a finned cylinder during the solidification (energy recovery) of a non-gray, non-opaque phase change material. Transient heat transfer in a symmetric, two-dimensional design is considered. The radiative transport equation is solved by using the Discrete Ordinate Method (DOM) while Finite Volume Method is used to discretize and solve equations for the conservation of mass, momentum, and energy. It was found that energy recovery time can be reduced by 74% by controlling the optical thickness property of the PCM with embedded radiation absorbing
