ASSESSMENT OF A CFD MODEL FOR THE SIMULATION OF FAST FILLING OF HYDROGEN TANKS WITH PRE-COOLING
High gas temperatures can be reached inside a hydrogen tank during the filling process because of the
large pressure increase (up to 70-80 MPa) and because of the short time (~3 minutes) of the process.
High temperatures can potentially jeopardize the structural integrity of the storage system and one of
the strategies to reduce the temperature increase is to pre-cool the hydrogen before injecting it into the
tank. Computational Fluid Dynamics (CFD) tools have the capabilities of capturing the flow field and
the temperature rise in the tank. The results of CFD simulations of fast filling with pre-cooling are
shown and compared with experimental data to assess the accuracy of the CFD model
