Numerical investigation of the vortex tube performance in novel precooling methods in the hydrogen fueling station

Jianye Chen et al.

Summary: This study investigates the potential of integrating a Ranque-Hilsch vortex tube (RHVT) in the precooling process for refueling high-pressure hydrogen vehicles at hydrogen refueling stations.
