The BRL-Q1D code is a computer program that uses quasi-one-dimensional, adiabatic, inviscid, numerical algorithms to solve the Euler equations. The governing equations are derived for arbitrary geometry and transformed into a uniform computational grid. An implicit Beam-Warming solver and an explicit MacCormack solver are employed. The input requirements, the code structure and the output options are discussed. Various flow calculations with the BRL-Q1D code are verified against experiments. Calculations are performed using the experimental geometries and test conditions of a conventional shock tube, a small-scale blast-simulator model and the large blast simulator at the experimental data validates the numerical flow simulation. In addition, two methods are discussed which are helpful for improving the computational prediction.

Recently, there have been significant advances in the fields of high-enthalpy hypersonic flows, high-temperature gas physics, and chemistry shock propagation in various media, industrial and medical applications of shock waves, and shock-tube technology. This series contains all the papers and lectures of the 19th International Symposium on Shock Waves held in Marseille in 1993. They are published in four topical volumes, each containing papers on related topics, and preceded by an overview written by a leading international expert. The volumes may be purchased independently.
