摘要 The shock-induced ignition and detonation wave propagation in reactive elliptic premixed bubbles are numerically studied.Close attention is paid to the bubble geometry effect on the ignition pattern and the ensuing bubble behavior.Five elliptic bubbles with different aspect ratios are examined.According to the numerical results,three typical ignition patterns are identified under the same incident shock strength and the underlying mechanisms are interpreted.The difference in ignition pattern shows that,comparing with the inert shock-bubble interaction,the geometry effect in reactive shock-bubble interaction(RSBI)has more implications.In addition to the aspect ratio,the ignition location and the distance from the ignition spot to the nearest/farthest bubble surface should also be considered as elements of the geometry effect in RSBI.
