The Air-Blast-Induced Environment Within Civil Defense Blast-Slanted Shelters

Abstract

The objective of this work unit was to review and discuss the application of hydrodynamic codes in the Office of Civil Defense (OCD) shelter research program, and then consider the development of a conceptual model of the flow into and through blast-slanted basement shelters. The review selected a two-dimensional Eulerian code which numerically simulated inviscid, compressible flow without heat transfer. This form of code was shown to be the most suitable form of code for OCD needs on a cost-effectiveness basis. The Eulerian equations were discussed, linked to their numerical form, and a complete set of numerical equations was appended for the reader's convenience. To provide the basis for the evaluation of this approach to future OCD problems a brief review of the internal workings of this form of code was undertaken. A bibliography was provided which will allow the reader to expand the brief review provided by this work unit.
