shock tunnel

shock tunnel

[′shäk ‚tən·əl]
(engineering)
A hypervelocity wind tunnel in which a shock wave generated in a shock tube ruptures a second diaphragm in the throat of a nozzle at the end of the tube, and gases emerge from the nozzle into a vacuum tank with Mach numbers of 6 to 25.

studied spiked blunt body drag in a hypersonic shock tunnel and showed that drag reduction significantly decreased as attack angle increased.
But, the frequency of vibrations in a metallic diaphragm-explosion-driven test facility, such as a shock tunnel, is generally very high and a measurement technique deployed can work successfully if the sensors have a moderate operating frequency In other words, a mismatch must exist between the natural frequency of the model and the operating frequency of the sensors to carry out measurements in hypersonic impulse facilities [1].

Other researchers also have noticed that coaxial thermocouples are more robust and durable as compared to thin-film sensors when it comes to the application of measuring the heat flux in the harsh environment [9, 10] Moreover, thermal sensors are routinely used in shock tunnels, expansion tubes, free-piston shock tunnel, and gun tunnels [11].
The simplest Reflected Hypersonic Shock Tunnel is a shock tube equipped with a convergent-divergent nozzle to produce high Mach number and high enthalpy flows in the test section close to those encountered during the atmospheric flight of the 14-X B at hypervelocity.
