Refinement of DISPRE2 Quality-Distance Software

摘要

The DISPRE2 model, developed by Southwest Research Institute (SwRI), has been refined under a contract to the U.S. Army Engineering and Support Center, Huntsville, and the Klotz Club to allow final Klotz Club approval of the use of the model for loading densities less than or equal to 1.0 kg/cubic meter. DISPRE2 predicts the hazardous debris density and air blast at any given distance following an accidental detonation in an arch-shaped or rectangular above-ground ammunition magazine storing up to 5,000 kg of TNT equivalent explosives material. Version 1.0 of DISPRE2, completed in October 1994 for the Klotz Club (an informal working group composed of delegates from eight countries with common concerns in safe explosives storage) was introduced at the 1994 DOD Explosives Safety Seminar. Subsequent expansion of the model was presented at the 1996 DOD Explosives Safety Seminar. Since that time, modifications and refinements have been recommended by a users working group which met in August 1996 and a technical working group meeting in December 1996. These changes have now been implemented into Version 2.5 of the software. Examples of the modifications include the incorporation of an updated version of the BLASTX code, changes to the shape of the debris density contours, refinement of the treatment of earth cover and debris roll, and the addition of input warning flags. All refinements to DISPRE2 Version 2.5 and their effects on the resultant output are presented in this paper.
