Abstract

In this study, the thermal behavior in a Type IV hydrogen storage tank during fast charging was investigated by establishing a 2-dimensional axisymmetric model. The thermal properties of the real high-pressure hydrogen were considered and obtained from REFPROP software. The computing mesh with 15312 girds, the time step of 0.001 s, and the Realizable k-ε turbulence model were chosen to simulate high-pressure hydrogen charging. The developed numerical model was validated through rapid charging experimental data, with the maximum computational error being limited within ±2%. Different charging parameters of the charging pressure mode, charging temperature mode, and precooling method on the thermal performance of on-board hydrogen storage... (More)

In this study, the thermal behavior in a Type IV hydrogen storage tank during fast charging was investigated by establishing a 2-dimensional axisymmetric model. The thermal properties of the real high-pressure hydrogen were considered and obtained from REFPROP software. The computing mesh with 15312 girds, the time step of 0.001 s, and the Realizable k-ε turbulence model were chosen to simulate high-pressure hydrogen charging. The developed numerical model was validated through rapid charging experimental data, with the maximum computational error being limited within ±2%. Different charging parameters of the charging pressure mode, charging temperature mode, and precooling method on the thermal performance of on-board hydrogen storage tanks were investigated. It was found that when the precooling temperature is set as −20 °C and −40 °C, the temperature rise of hydrogen storage tank can meet filling requirement. The fast-slow + initial precooling and slow-fast + later precooling modes are optimized. This work may supply some new insights on the thermal response of on-board hydrogen storage tanks during rapid charging.
