A shock tube, vertically mounted, contains a liquid in the lower driver section; the upper driven section is either filled with gas at some selected pressure or is vented to atmosphere. The liquid is heated under pressure such that boiling is prevented; it is then suddenly decompressed by the bursting of a diaphragm separating the driver from the driven section. As the diaphragm breaks, a decompression pulse is propagated downward through the fluid; at the same time, the heated liquid will start to vaporize at the interface and will eventually discharge vapor into the driven section. Pressure-time recordings are taken at different stations, along the tube; the results obtained within the driver section allow a comparison of the propagation and attenuation of the decompression pulse in cold water and preheatcd water. From pressure records taken at the driven section, vaporization proceeds at a rather slow rate, and independently of the wave motion ensuing diaphragm rupture. (auth)
