What is shock tubes?

A shock tube is a closed vessel designed to study the behavior of fluids and gases under high-pressure, high-temperature, and high-velocity conditions. It is made up of a long, cylindrical tube with a diaphragm, which separates the two compartments filled with different gases.

To create a shock wave, the diaphragm is ruptured rapidly, causing a sudden and intense pressure change in the gas. This creates two distinct regions within the tube - the driver section and the driven section. The driver section is the portion of the tube where the gas is compressed and heated by the shock wave, while the driven section is the area where the test gas is located, which is subjected to the high-pressure and high-temperature conditions created by the shock wave.

Shock tubes are widely used in various industries and research fields, including aerospace, combustion, and materials science. They allow scientists to simulate and study extreme conditions that cannot be achieved using traditional methods.
