Abstract

A numerical study to investigate the behaviour and impact of different inner tube geometric shapes on the thermal performance of the latent heat thermal energy storage (LHTES) unit have been done. Current work includes a horizontal concentric shell filling with paraffin wax as phase change material (PCM). The tested inner tube geometric shapes were circular tube, horizontal elliptical tube, and vertical elliptical tube. Finite-volume method with a single-domain enthalpy method have been used for the simulation. The results showed that the circular tube is the best due to keeping absorbing heat from PCM through HTF for a long time with 66.37% efficiency and 240.5 minutes.
