Precursor Waves in Shock Tubes
The Physics of Fluids, 1963Weymann's observation of a wave of electrons propagating from a strong shock into the region ahead of it is considered. By taking into account the mutual electrostatic repulsion of the electrons through a simple approximation, the main features of the precursor wave motion can be explained.

Journal of Physics E: Scientific Instruments, 1984
A pneumatic valve has been designed to replace diaphragms in shock tubes and a diaphragmless shock tube has been constructed for use with the pneumatic valve. Performance tests have been carried out for the shock tube. The present apparatus is shown to be capable of producing shock waves up to 3.5 in Mach number and be convenient to use.

Electric Shock-Tube Experiment
American Journal of Physics, 1966A small-diameter linear shock tube suitable for laboratory demonstration is described in this paper. Necessary construction details are given along with a discussion of the instrumentation required to measure the velocity of the luminous shock front, the flow velocity of the expanding plasma, and the conductance of the plasma.

A shock tube is a device in which a shock wave is normally formed by the rupture of a diaphragm, which divides a gas at high pressure from a test section containing the species of interest at a lower pressure. The shock wave brings the test gas virtually instantaneously to a known high temperature and pressure, maintains that condition for a time and ...

Review of Scientific Instruments, 1966
Several different high explosive driven shock tubes have been developed as sources of short duration, supersonic, high pressure pulses which can be used to load large, massive objects with accelerations up to many thousand g's. These shock tubes are particularly appropriate for simulating strong blast effects on hardened structures.

Publisher Summary This chapter discusses the nature of shock-tube flows with emphasis on their capabilities and limitations. Existing instrumentation for measuring the state of the shock-processed gas sample will be described and many examples of the application of shock tubes in studying the physics and chemistry of high temperature gases will be ...

Shock Tube Induction Flowmeter
Review of Scientific Instruments, 1965Shock tube gas velocities have been monitored accurately by means of a transverse-field induction flowmeter. Experiments were performed in a hydrogen-driven shock tube using argon as the test gas; shock Mach numbers were varied from 6 to 12, initial pressures from 0.5 mm Hg to 50 mm Hg, and magnetic field strengths from 0 to 1100 G.

Abstract : This work was undertaken to increase the understanding of the fluid dynamics of shock wave reflection phenomena. Parametric height-of-burst (HOB) experiments were performed to establish a consistent set of HOB peak overpressure curves in the low pressure regime (< 100 psi) for hydrodynamically smooth and rough surfaces.

The feasibility of using a shock tube for quantitative investigations of hypersonic flow phenomena at temperatures simulating free flight conditions is studied theoretically and experimentally. In the theoretical part, various aspects of the hypersonic shock tube problem are treated in logical order.
