Storage Characteristics

Experimental system on thermal energy storage characteristics of phase change materials (PCMs) in annular space of a vertical double-pipe heat exchanger was set up. The thermal storage performance of paraffin and paraffin/expanded graphite composite PCM with the mass fraction of 70% paraffin was compared. The Fluent software was used to simulate the temperature field of the composite PCM during the thermal storage process. The results show that, for the paraffin, in the sensible heat storage phase, because the heat transfer process is controlled by the heat conduction, the temperature in paraffin gradually reduces from the inside to the outside of the annular space. But for the phase change thermal storage phase, solid-liquid phase change heat transfer is controlled by natural convection and the effect of buoyancy, the temperature in paraffin reduces from top to bottom, from the inside to the outside of the annular space. For the composite PCM, heat transfer is controlled only by the heat conduction process, both the sensible and latent heat storage process, the temperature in the composite PCM decreases from bottom to top, from inside to outside of the annular space. As the thermal conductivity of composite PCM is 15.65 times of paraffin, the thermal energy storage time is shortened by 86.6% than paraffin. The temperature fields of composite PCM in different time are obtained by numerical simulation method, the measured temperatures and simulation results are in good agreement.

Phase Change Materials (PCM) exhibit a thermal storage property by their latent heat of fusion. These PCMs absorb heat energy from the source and they undergo a change of phase and release the stored heat energy to the application when required. This research work focuses on utilizing this property of PCMs to store heat energy from a steam source from a Parabolic Trough Collector, and the output from such a Thermal Energy Storage Unit could be used for steam cooking. This research work selects the optimum Phase Change Material to suit the heating application and virtually simulates the performance of various configurations of Thermal Storage heat exchangers and finds the optimum number of passes for steam flow using the Computational Fluid Dynamics (CFD) approach.
