Effects of longitudinal disturbances on two-dimensional detonation waves

Abstract
We perform simulations of propagation dynamics of cellular detonations in disturbed media. Upstream density variations impose periodic oscillations of the average leading shock pressure and detonation cell scales. Mode-locking of detonation dynamics still occurs in cellular detonations both for regular and irregular detonations under a large disturbance wavelength.
