Comparing trapezoidal and circular configurations to evaluate the impact of shell geometry on thermal energy storage performance (opens in new tab)

This research investigates the influence of shell and inner tube geometry modifications on the thermal performance of latent heat thermal energy storage (LHTES) systems employing phase change materials (PCMs), aiming to overcome the low thermal conductivity and weak melting zones commonly observed in conventional configurations. Several shell-and-tube configurations with circular, rectangular, and trapezoidal geometries were investigated numerically. The novelty of the present study lies in t...
