Thermo-physical Characterization and Performance Evaluation of Castor Oil as a Sensible Heat Storage Medium in a Box-Type Solar Cooker
Box-type solar cookers (BSCs) provide a clean alternative to conventional biomass fuels, but their operation is limited by intermittent solar radiation. This study investigated castor oil as a sensible heat storage (SHS) medium for improving thermal performance and post-solar heat retention. The castor oil had a densit...
