Abstract:
This report describes a method for the calculation of parts of a spherical blast field from pressure history observations at stations placed at various distances from the blast center. The method consists of a determination of the pressure field by model fitting and of a subsequent numerical integration of the flow governing equations. The results provide a complete flow description pressure, density, and particle velocity as well as estimates of the accuracy of the results within the region of observations. A check of some basic assumptions spherical symmetry and negligible viscosity is provided by an independent calculation of the particle velocity. Application examples are shown for a theoretically computed strong blast field and for data from a high energy blast experiment.
