Abstract

The physics of grain dust ignition and combustion in a high-temperature atmosphere behind a shock wave is numerically studied using an Eulerian description of the two-phase flow system. Corn starch is used as a dust in the present calculation. Unsteady two-dimensional conservation equations of mass, momentum, and energy are integrated in the form of Euler equations for both gas and solid phases using a TVD-upwind method. Results show that the calculation with an one-step overall corn starch/air reaction mechanism gives the two-phase C-J detonation velocity, the ignition and transition to detonation, and the two-phase detonation features; it is found that the two phases have large lags in temperature and velocity fields.
