Abstract:

A computational study was performed with the BRL-Q1D code to determine the expected performance characteristics fo the proposed U.S. Large BlastThermal Simulator LBTS. 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 157 scale, axisymmetric, single-driver model of the LBTS. 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 LBTS design.
