An Adaptive Gridding Approach to the Computation of Reactive Two-Phase Flows in Two Dimensions
In this paper we outline the application of adaptive gridding techniques to the calculation of reactive two-phase flows in two dimensions, in the context of Interior Ballistics. Computations of these flows on a single mesh, using a higher order shock-capturing Riemann problem based scheme, are presented and compared with experimental data. While encouraging agreement between the two is achieved the need for an adaptive approach to the problem is recognised. It is proposed that a scheme based on Adaptive Mesh Refinement is desirable. The algorithm for the adaptive scheme is described and validation tests are performed for the gas-phase (Euler) equations. The implementation of the adaptive scheme in the case of the full two-phase system is discussed.
