Experimental investigation of PCM spheres in thermal energy storage system
(Trans Tech Publications, 2013)
This paper presents the experimental result of a small scale packed bed of random spheres
with encapsulated PCM being charged and discharged. A vapor compression refrigerator and heated
room with fan heater were used to ...
Effectiveness–NTU correlation for low temperature PCM encapsulated in spheres
(Elsevier Ltd., 2012-05)
The applicability of the effectiveness–NTU method for characterising a PCM thermal energy storage system was experimentally investigated. The system consisted of PCM encapsulated in spheres with a liquid heat transfer ...
Investigation of conducting pins in sphere filled with phase change material for enhancing heat transfer in thermal energy storage
(Trans Tech Publications., 2012)
The utilisation of phase change material (PCM) for thermal energy storage (TES) can significantly enhance the energy savings achievable with renewable thermal systems. Sphere based packed bed systems have been used as TES ...
Effective thermal conductivity for melting in PCM encapsulated in a sphere
(Elsevier Ltd., 2014-06)
Heat transfer in phase change materials (PCMs) contained in spherical encapsulations can be modelled more simply if an effective thermal conductivity can be determined to represent the natural convection occurring within ...
