Abstract
The propagation of detonation in a liquid explosive (nitromethane) that has been precompressed by a shock wave is investigated experimentally. An explosive donor charge is used to transmit a shock wave into a capsule containing a tube of test explosive (sensitized nitromethane) perpendicular to the direction of the compressing shock wave. The shock wave compresses the liquid in the test capsule, then reflects from a steel anvil and further compresses the liquid. A detonation then propagates through the tube of shock‐compressed liquid at velocities as large at 7.5 km/s. Propagation of the detonation is recorded with an electronic streak camera, and the degree of compression is measured using a manganin gauge. The observed velocity as a function of the degree of compression is compared to predictions of detonation velocity as a function of density.
