BLAST WAVE AND FIREBALL AFTER HYDROGEN TANK RUPTURE IN A FIRE
The development of computational §uid dynamics (CFD) model to simulate blast wave and ¦reball dynamics after high-pressure hydrogen tank rupture in a ¦re is described. Parametric study is performed to de¦ne the e ̈ect of submodels, numerical methods, and parameters on the convergence of the simulations and reproduction of experimental data. Experiments with initial pressure in hydrogen tank of 350 and 700 bar were used to validate the model. The e ̈ect of hydrogen combustion and tank opening on the blast wave strength is assessed. The simulated cases include instantaneous tank opening and half tank opening.
