Fundamental Study on Operational Parameters of Diaphragmless Shock Tube
MATEC Web of Conferences, 2018 This paper shows influences of initial conditions on a diaphragmless shock tube operation. This facility consists of a driver tube, a driven tube and a damp tank. The driver tube has a circular cross section with diameter of 150 mm and the driven tube, a

Electron Beam Measurements of Density in Shock Waves Reflecting From a Cold Wall [PDF]
, 1968 The normal shock wave is a rarefied-gas flow in which large departures from thermodynamic equilibrium and strong non-linearities occur and it is the simplest such flow due to its one-dimensionality and the absence of solid boundaries.

The Physics of Fluids, 1973 Two shock tubes have been developed which allow for partial or full immersion of the test sections within a cryogenic bath. One tube is used for the study of shock-wave interactions with strong density gradients, and the other to obtain very large shock Mach numbers with ideal gas conditions in all flow regions.

A chemical shock tube driven by detonation
, 2012 A chemical shock tube driven by a detonation driver is described in the present paper. This shock tube can produce a single controlled high-temperature pulse for studies of gas-phase reaction kinetics, but the difficulty associated with the timing for ...

Study on Dynamic Response of Downhole Tools under Perforation Impact Load
Shock and Vibration, 2017 A model of a multibody system is established to investigate the dynamic response of an oil tube-shock absorber-perforating gun system in downhole perforation-test joint operation. In the model, the oil tube and perforating gun are modeled as elastic rods
