Diffraction of weakly unstable detonation through an obstacle with different sizes and shapes
Yuan Wang, Zheng Chen, Haitao Chen
Abstract
Two-dimensional simulations considering detailed chemistry are conducted to investigate the weakly unstable detonation diffracting through an obstacle. Subcritical, critical, and supercritical regimes are identified and their distributions are significantly affected by the obstacle size and shape. In contrast, the mixtures with different nitrogen dilution have little influence on the regime distributions.
