Finite Difference Calculation of the Behavior of a Discontinuous Signal Near a Caustic,
Abstract
It is important to predict sonic boom overpressure signatures in the vicinity of a caustic. In particular, one needs to be able to calculate the overpressure when the caustic surface intersects, or when it is near the ground. While the analytical formulation of this problem is a simple one, the solution by formal mathematical techniques presents great difficulties. Consequently, there is great impetus for developing numerical techniques that can provide such predictions. Here the authors report on the extension to the caustic problem of a technique developed by Murman and Cole for transonic flows. (Author)
