Numerical simulation performed to investigate the behaviour of the high pressure hydrogen jetting of air. High pressure hydrogen (30–40 bars) was injected to air at atmospheric pressure through 2 mm orifice. Numerical simulations were performed with Kiva3V code with 2D axisymmetric geometry. The auto ignition of high pressure hydrogen release was previously observed in laboratory tests [1-2] and suspected as possible cause of some accidents. Numerical simulations showed that auto ignition of high pressure hydrogen to air are possible due to molecular diffusion. Auto ignition was predicted at hydrogen-air contact surface due to mass and energy exchange between high temperature hydrogen and air heated by shock wave. |
