Summary

The mixing of liquid oxygen and liquid hydrogen was simulated. The non-reactive mixtures were obtained by injecting jets of the oxidizer or simulant into a pool of the fuel or simulant. Three fluid combinations were tested: liquid oxygen into liquid helium, liquid nitrogen into liquid helium, and liquid nitrogen into liquid hydrogen. Results showed that the jet fluid stays coherent throughout the mixing process and that peak boiling of the pool fluid occurs shortly after jet impingement. Estimates of bulk density indicate a smaller range of variation than is currently used for explosive yield calculations.
