Thermal Performance Analysis of LaNi₅ Metal Hydride Reactors Using Multiple Heating-Tube Configurations and Fin Enhancements

Metal hydrides such as LaNi₅ offer a compact and intrinsically safe hydrogen-storage solution for PEM fuel cells, but their endothermic desorption reaction requires efficient heat delivery to maintain acceptable release rates. This study numerically investigates the thermal performance of a cylindrical LaNi₅ metal hydr...

Thermal performance optimization of biomass-fired ovens using computational fluid dynamics: A Case study of coconut shell briquette production in Indonesia

Uniform heat distribution is essential for staged drying of coconut-shell briquettes because temperature overshoot can induce thermal shock and reduce product quality. This study evaluated the thermal performance of an industrial biomass-fired briquette oven using transient computational fluid dynamics (CFD). The oven...

A Comparative Study on the Thermal Performance of Copper and Stainless-Steel Heat Pipes

Heat pipes are highly efficient passive thermal devices that exploit phase-change mechanisms —evaporation and condensation of a working fluid—to transport heat with minimal temperature drop. This study presents an experimental and computational investigation of a 204 mm copper–water heat pipe equipped with a stainless-...
