ANALIZA CIEPLNA I WYTRZYMAŁOŚCIOWA NISKOCIŚNIENIOWYCH ZBIORNIKÓW DO MAGAZYNOWANIA WODORU

The article presents numerical analyses of the strength and operating conditions of low-pressure Metal Hydride Storage tanks (MHS) designed for hydrogen storage. The exothermic process of filling the tank with hydrogen and the endothermic process of its discharge were investigated. Thermal analysis of the tanks was carried out without additional cooling/heating of the tank (depending on the tested process) and with the use of a water bath to regulate the temperature of the object. The amount of heat generated in filling the MH storage tank and its deficit during its emptying were also determined. The strength analysis of the tank structure under the influence of static loads is also presented. Simulations were performed using ANSYS Mechanical and ANSYS Fluent software. The obtained results confirmed the correctness of the adopted design assumptions and simplifications in the development of the numerical model of the tank.
