Self-Ignition of Hydrogen in a Pipe by Rupture of Pressure Boundaries

파열 압력경계 조건에 따른 파이프 내에서의 수소 자발 점화

Numerical simulations are conducted to investigate the mechanism of spontaneous ignition of hydrogen within a certain length of downstream pipe released by the failure of pressure boundaries of various geometric assumption. The results show that local ignition is developed in limited area such as boundary layer and the mixing of hydrogen and air is weak at the planar pressure boundary conditions, whereas the flame fronts at the contact region are developed at the pressure boundaries of the spherical shape.
