A model to simulate thermal behaviour of an onboard storage tank and parameters of hydrogen inside the tank during fuelling is presented. The energy conservation equation, Abel-Noble real gas equation of state, and the entrainment theory are applied in the model to reproduce the experimentally recorded dynamics of hydrogen temperature inside the tank and distribution of temperature through the wall. Convective heat transfer between hydrogen, tank wall and the atmosphere are modelled using Nusselt number correlations. An original methodology, based on the entrainment theory, is devised to calculate changing velocity of the gas inside the tank during the fuelling. Conductive heat transfer through the tank wall, composed of load-bearing carbon fibre reinforced polymer and a layer of liner, is modelled by employing one-dimensional unsteady heat transfer equation. The model is validated against experiments on fuelling of Type III and IV composite tanks for onboard hydrogen storage. Hydrogen temperature inside a tank is predicted by the model within the experimental non-uniformity of 50C.
