Development of Sharp Discontinuity Tracking Methods for Explosion Problems,
Abstract
This report summarizes the development of a new numerical method called sharp discontinuity tracking for predicting the flow field arising in explosive blast problems. This method uses standard finite difference techniques for smooth regions of the flow, but treats physically important shocks and contact discontinuities as explicit surfaces (internal boundaries) which remain sharp (not smeared) as the computation progresses. The method is applied to explosion problems in one space dimension (spherical symmetry) and two space dimensions (axial symmetry). (Author)
