Abstract

Abstract

A two-dimensional mathematical model of viscous aluminum/air two-phase detonation is established. The flow field inside the detonation tube was calculated by the method of conservation element and solution element. And the distribution of physical parameters is analyzed. Numerical results show that in the early stages of the deflagration-to-detonation transition process in the tube, pressure change obviously along the radius and significant reflection wave is collided off the wall. In the later period, pressure along the axis changes obviously, but the radial effect still can't be ignored. The reflection wave from the collision is important on the formation of steady detonation wave. Numerical results also show that the initial radius of the aluminum powder particles have certain influence on the formation and propagation of detonation wave. And certain influence of gas viscosity on flow field near the wall in the detonation tube was exerted. The results of the study can be utilized to reveal the mechanism of the deflagration-to-detonation transitim.
