Numerical Study on Propagation of Explosion Wave in H2-O2 Mixtures
Two-dimensional computations of the propagation of the explosion wave in a mixture of hydrogen and oxygen are performed using WENO finite difference scheme with fifth order accuracy and two-step chemical reaction model. Numerical results show that obstacles setting repeatedly along the path of the flame propagation process obviously can accelerate the flame. The mechanism of the accelerating effect is attributed to the positive feedback of the turbulence region induced by obstacles for combustion process.
