Abstract : Presented theoretically and experimentally are (1) the feasibility of simulating a nuclear blast environment by detonating a gas and (2) determination of the initial conditions of hydrogen-oxygen mixtures to yield blast waves of the same pressure-velocity relationship as that in air shock waves. When the theory was derived by predicting the characteristics of the simulated blast waves, a computer program was written. Experimental data were used to adjust the computed data. The experiments were conducted in a 13-inch-diameter, high-pressure shock tube and yielded four mixtures of hydrogen and oxygen capable of simulating shock waves with overpressures of from 300 to 1,200 psi. It was found that detonation waves may be substituted for air shock waves when the incident loading is important and that applications are generally limited to instances in which only one characteristic of an air shock is simulated.
