Two Dimensional Convective Flamespreading in Packed Beds of Granular Propellant
Abstract
A theoretical model is described for the digital simulation of flame spreading and pressure-wave propagation in axisymmetric, two dimensional propelling charges. The approach recognizes explicitly the presence of internal boundaries defined by jumps in porosity and allows for treatment of the influence of bag materials, liners, and additives on flame spreading. As one step toward the implementation of this model, a technique of numerical solution is presented for a geometrically complex region of two dimensional, two phase flow. Solutions are presented for three problems based on nominal data.
