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
particles.
Index Terms—Phase change material, radiation,
solidification, thermal energy storage module.
