Electromagnetic hydrophone for pressure determination of shock wave pulses

Ultrasound in Medicine & Biology, 1997
An electromagnetic hydrophone has been designed and tested to determine its ability to measure shock wave pulses similar to those produced by lithotripter machines. The principle of operation of the hydrophone, its design and performance are described.

Dwell Time Distribution Behind Reflected Shocks in a Single Pulse Shock Tube

Israel Journal of Chemistry, 1974
AbstractThe variations of the dwell time along the sampling zone of a single pulse shock tube, the expansion of the reaction mixture, and the change in its position during the cooling process are discussed. A method to evaluate a correct space average dwell time is described.

Shock waves in laser-pulse-irradiated metals

Applied Physics A Materials Science & Processing, 2001
In an earlier paper [1] the temperature as a function of time and distance from the surface of a metal after the application of a laser pulse had been calculated. The assumption was made that only heat conduction is responsible for the dissipation of energy provided that the input fluence of the laser pulse is below the threshold for ablation.

Shock-timing experiments using double-pulse laser irradiation

Physics of Plasmas, 2006
The timing of multiple shock waves is crucial to the performance of inertial confinement fusion ignition targets. Presented are measurements of velocities and optical self-emission from shock waves in polystyrene targets driven by two 90-ps pulses separated by 1.5–2ns.

Shock train response to pulse backpressure forcing

The Aeronautical Journal
Abstract Transient numerical simulations were conducted to investigate the influence of large amplitude and fast impact backpressure on a shock train. The fundamental problem consists of a shock train within a constant-area channel with a Ma=1.61 inflow and a pulse backpressure applied to the outlet.

Short-Pulse Laser-Driven Strong Shock Waves

2018
Warm Dense Matter (WDM) or the High Energy Density (HED) states are useful for instance, to describe properties in giant planets. They are usually achieved in laboratory conditions by using high energy (hundreds of J) and long duration (ns) lasers. An alternative for creating matter in extreme states is described in this chapter.

Bio-inspired pulsed power switch under shock wave

Journal of Physics D: Applied Physics
Abstract The spark gap switch is a crucial component in the primary energy drive system for large pulse power devices. The switch electrodes are composed of high-density artificial graphite, possessing excellent erosion resistance. However, insufficient mechanical strength in the graphite electrodes makes them especially susceptible to ...

Generation of cushion curves from one shock pulse

Packaging Technology and Science, 1994
AbstractThree methods for generating performance information relative to the shock absorbing ability of cushioning materials are discussed. The conventional method, which follows the test standard ASTM D1596, requires enormous amounts of test data and can be quite expensive in material costs, laboratory time and equipment.
