AB  - Solar energy is a renewable energy source that can generate electricity, provide hot water, heat for
houses and lighting for buildings. Paraffin wax is cheap and has moderate thermal energy storage density.
Commercial paraffin wax grade A was used as Latent Heat Storage (LHS) is placed in a vertical cylindrical Heat
Storage Container (HSC) and a central single pipe through which cooling water is passed for heat exchange
from down to up of the HSC. Heater resistance tape placed outside the container used for supply the heating
to wax. In this setup, the phase change characteristics of wax during solidification are measured by monitoring
the radial and axial temperature profiles within the container, the effect of using finned heat exchange pipes is
also examined. In an attempt to gain extra heat storage, a sensible heat material consisted of an open-ended wire
mesh cylinder made out of steel is embedded in the sample, this enabled to find its effect on the speed of
solidification of wax. Experimental results are presented to show the variation of solidification speed along radial
sections. Comparison with theoretical predictions derived from freezing model of ice is given. The results of this
research also show the advantages of finned heat transfer pipes.
