Abstract

A numerical model was established based on the actual structure of vehicle-mounted liquid hydrogen cylinders in order to study the thermal conduction safety of the cylinders during the storage and transportation of large-volume vehicles. The internal temperature and heat flux changes of the cylinders were simulated and analyzed under the coupling changes of single parameters and multi-parameters under the start-stop conditions of the cylinders under various environmental temperature, pressure, and acceleration conditions. The findings demonstrate that the heat flux in the cylinder increases as acceleration increases when a single parameter is changed. The heat flux falls as cylinder pressure rises; the heat flux increases with increasing room temperature. When there is a two-factor coupling, an increase in acceleration reduces the impact of ambient temperature decrease on the heat flux in the cylinder while simultaneously enhancing the impact of pressure increase; an increase in pressure reduces the impact of an increase in ambient temperature on the heat flux in the cylinder. It offers a theoretical foundation for the safe application of large-volume liquid hydrogen cylinders installed in vehicles.
