Numerical Simulation of H2/Air Detonation Wave Around Obstacles Using Detailed Reaction Models
Description
To observe the break up and re-generation of the detonation cell structure, a 2-D computation of detonation propagating around a circular obstacle was conducted. FEFLO with detailed chemical reaction model was applied to this 2-D simulation. The various blockage ratios between the tube width and the obstacle diameter were tested to investigate the effect on the break up/re-generation of the detonation cell structure. In this study, the detonation wave propagation was highly affected when the blockage ratio became larger. The simulation captured the break up and re-generation of the detonation cell structure behind the obstacle.
