Abstract:

The experimental was entirely devoted to developing the experimental technique. In this technique superheated states are produced by sudden adiabatic depressurization of fluids whose initial state lies on the liquid-vapor co-existence curve, as is done on a more modest scale in bubble chambers. The technique is still being perfected and although it appears to be feasible and nearly functional, no data have yet been taken. Significant degrees of superheat have been obtained for several milliseconds. The theoretical phase, on shock and detonation instabilities, appears to have successfully shown the connection between transverse wave instabilities and the observed three-dimensional structure of detonation waves. It indicates that such transverse wave structure might be expected in all detonation waves and that it is caused by a modified form of the transverse wave instability predicted for shocks in inert materials. Originator supplied key words include Lasers, Vapor explosions, Superheated liquids, Detonation waxes, and Shock waves.
