Performance Predictions for the Large Blast/Thermal Simulator Based on Experimental and Computational Results

Abstract

A computational study was performed with the BRL-Q1D code to determine the expected performance characteristics fo the proposed U.S. Large Blast/Thermal Simulator (LB/TS). This computational study complements an earlier experimental parametric study which was performed in the 25.4-cm shock tube located at the BRL. For the experiments, the BRL 25.4-cm shock tube was configured as a 1:57 scale, axisymmetric, single-driver model of the LB/TS. This report documents two computational parametric studies which were performed to determine the range of nuclear blast simulations available with the current LB/ TS design. The first parametric study s a comparison with existing experimental data to validate the computational model and to determine the limits of its accuracy. The second parametric study used the validated computational model to predict the operating range of the LB/TS design.
