Book Description
Pressure measurements at three different locations in the driver section of a shock tube reveal that the expansion wave generated by diaphragm rupture can be effectively viewed as a simple centered expansion wave whose origin is slightly shifted with respect to the origin of an ideal x-t diagram. The resulting centered expansion wave is used to study the condensation of water, heavy water, benzene, carbon tetrachloride and Freon 11, in an excess of the non-condensing carrier argon. Simultaneous pressure and light scattering measurements determine the onset of condensation. The isentropic flow within the expansion wave is found to be preserved up to the point of the detectable onset of condensation by tailoring the onset conditions to occur at the tail of the expansion wave, thus rendering a simple analysis of the experiments possible.

Book Description
A critical appraisal is made of the design, research, development, and operation of the novel UTIAS implosion-driven hypervelocity launchers and shock tubes. Explosively-driven (PbN6-lead azide, PETN-pentaerythritetetranitrate) implosions in detonating stoichiometric hydrogen-oxygen mixtures have been successfully developed as drivers for hypervelocity launchers and shock tubes in a safe and reusable facility. Intense loadings at very high calculated pressures (almost megabar range), densities (g/cc) and temperatures (thousands deg K), at the implosion centre, cause severe problems with projectile integrity. Misalignment of the focal point can occur and add to the difficulty in using small calibre (6 to 8 mm dia.) projectiles. In addition, the extreme driving conditions cause barrel expansion, erosion, and possible gas leakage from the base to the head of the projectile which cut the predicted muzzle velocities to half or a third of the lossless calculated values. However, in the case of a shock-tube operation these difficulties are minimized or eliminated and the possibilities of approaching Jovian reentry velocities are encouraging. In a recent run using about 100g of explosive PETN and 400 psi 2H2 + O2 a shock Mach number approx. 60 was obtained in air at an initial pressure of 1 torr in 1.0 in. dia. shock tube channel. In addition, the use of focused, explosive-driven implosion waves may have many other physical and technological applications. (Author).
