“…The velocities decreased to about 500 m/s in around 2 µs, see figure 3. By analogy with the work of Karioris et al [4], who reported recovering an aerosol of fine metal particles post explosion of bridgewires, it is postulated that in the sub-bridgewire explosion regime only vaporisation occurs. The firing current-time profiles were time correlated to the PDV data.…”

Abstract. This is the second paper of three papers describing the studies to identify the initiating mechanisms in Exploding Bridgewire (EBW) detonators. In this paper the results of experiments to quantify the effect of the bridgewire explosion are described. Experiments have been performed to characterise the output from the bridgewire in terms of the stimulus it would apply to the surrounding explosive in an EBW detonator. The expansion speed of the bridgewire at burst as a function of input energy has been measured using Photonic Doppler Velocimety (PDV). To complement the bridgewire expansion velocity determinations aquarium experiments were carried out in which the shock wave velocity in water was measured, as a function of energy, by high speed photography. The shock pressures were calculated and compared to initiation criteria for PETN.

ABSTRACT:Aluminum, gold, platinum, and tungsten wires were investigated to determine the effect of the wire .iaterial on the initiation of PETN by exploding wires. The wires were exploded by a one microfarad capacitor charged to 2000 volts. The results indicate that favorable wire materials are those into which energy is deposited at a rapid rate.They also have low boiling points and low heats of vaporization.Heat

“…Pollutant combinations of presumed importance in air pollution effects are studied at experimental conditions that simulate those in the atmosphere and in the human respiratory tract. Experimental procedures include the generation of sub-micronic aerosols by an exploding-wire technique (Karioris, Fish, and Royster, 1962) and the use of radio-labeled gases to achieve increased sensitivity in sorption measurements. Interactions between SO2 and iron oxide aerosols are being considered initially, to be followed by studies of other systems.…”
