shock tube

[′shäk ‚tüb]
(fluid mechanics)
A long tube divided into two parts by a diaphragm; the volume on one side of the diaphragm constitutes the compression chamber, the other side is the expansion chamber; a high pressure is developed by suitable means in the compression chamber, and the diaphragm ruptured; the shock wave produced in the expansion chamber can be used for the calibration of air blast gages, or the chamber can be instrumented for the study of the characteristics of the shock wave.

There are many variations of shock tube design but all share a basic two chamber concept.
Thereafter, an off-engine shock tube test bench was used to create a simulated exhaust gas flow condition to investigate the impacts of the pressure wave and pulsating gas flow on the droplet breakup and spray distribution of an after-treatment injection using optical methods.
The present shock tube facility which has been described in details previously [20, 21] is consists of a 2000mm long driver section and a 7300mm long driven section, as shown in Figure 1.
In simulating the shock tube experiments the planar incident shock wave is initially situated at some distance upstream of the sphere.
Testing of the sensors in more realistic conditions is also available, using either the shock tube or a secondary facility, in which the dynamic pressure is generated within a liquid.

These specific applications consume large amounts of shock tube detonators, resulting in large amounts of plastic waste which has environmental impact.
The shock tube used in the program produce impulses in air that average 169.
The hot flash from the end of the shock tube then ignites the pyrotechnic composition in the delay element.
Nonel continues to find wide application and ICI has recently introduced a similar monoplastic shock tube initiating system called Excel.
Shock tube detonating systems are currently the main initiating system for mining explosives.
