正癸烷/空气旋转爆轰波形成与传播数值模拟
Numerical simulations of the formation and propagation of an n-decane/air rotating detonation wave
摘要
Abstract
To investigate the formation and propagation of a gas-liquid two-phase rotating detonation wave,three-di-mensional numerical simulations were conducted to discuss the formation and evolution characteristics and self-sus-taining propagation mechanism of n-decane/air rotating detonation wave using the Euler-Lagrangian method.The results reveal that the detonation and pressure waves with different intensities can be obtained by adjusting the ini-tial fuel distribution during the ignition stage.In the collision stage,four collisions occurred between the detonation and pressure waves.Owing to the lack of fuel supply,the pressure wave gradually decayed and disappeared,and the detonation wave propagated in a single-wave mode.In the stable propagation stage,the unburned fuel accumu-lated at the contact triple point to form an unreacted gas flow region and a local explosion was induced.The period-ic occurrence of the unreacted gas flow region and local explosion are important factors affecting the self-sustained propagation of two-phase detonation waves.关键词
