Stand-Alone Hemisphere-Tank Rupture in Tunnel Fire: Effect of Hydrogen Inventory on Blast Wave Strength in Far Field

Research output: Contribution to conferencePaper

Abstract

High-pressure hydrogen onboard storage rupture in a fire generates blast wave and fireball. These hazards are not yet investigated enough, especially in a tunnel. Consequences of such event, e.g. a blast wave, could be devastating depending on amount of stored hydrogen and tunnel dimensions. This raises the
question about the dependence of blast wave overpressure on hydrogen inventory in the tank. The problem is studied here numerically. Large eddy simulation (LES) turbulence model with the eddy dissipation concept (EDC) for combustion were employed in series of numerical simulations in three different tunnel cross-sections with four hemispherical tank volumes at pressures of 94.5 MPa. The dependence of blast wave overpressure on hydrogen inventory is defined. The results are conservative and require experimental validation in tunnel tests.
