Solidification Enhancement in a Triple-Tube Latent Heat Energy Storage System Using Twisted Fins

This work evaluates the influence of combining twisted fins in a triple-tube heat exchanger utilised for latent heat thermal energy storage (LHTES) in three-dimensional numerical simulation and comparing the outcome with the cases of the straight fins and no fins. The phase change material (PCM) is...
