Propagation of shock waves from source to receiver
This paper describes a 3-stage technique to model the propagation to the far field of nonlinear shock waves produced by high-energy explosive sources. The stages are: (1) a 3-dimensional unsteady Euler method for the strong shock near the source, including a Flux-Corrected-Transport (FCT) method, (2) the Nonlinear Progressive-wave Equation (NPE) procedure for the degeneration of the shock into a linear acoustical wave, and (3) the Parabolic Equation (PE) method for propagation to the far field. Comparisons of calculated data with a linear analytical method are shown.
