... thermal and exergy efficiency of an air heater was found to be 70.2 and 4.4%, respectively. The average overall thermal efficiency of carbon nanotubes + copper oxide-paraffin wax energy storage unit was 31.19%, with 11.9% as the average overall exergy efficiency. The energy storage increases the drying...

..., the effect of the composite heat energy storage material developed by the mixture of beach sand with paraffin wax is investigated. The experiments are carried out in solar still with composite heat storage material (SSCHSM), and results are compared with solar still with sensible heat storage material...

...S. M. Shalaby; A. E. Kabeel; E. El-Bialy; M. K. Elfakharany Low thermal conductivity is the main drawback of using paraffin wax as a latent heat thermal storage material in the solar air heater (SAH). In order to overcome this drawback, an absorber plate with extended surfaces through the paraffin...
