Shock Tube as an Impulsive Application Device

Impulse Generation by an Open Shock Tube

Weperformexperimental andnumerical studies of a shock tubewith an open end.The purpose is to investigate the impulse due to the exhaust of gases through the open end of the tube as amodel for a partially filled detonation tube as used in pulse detonation engine testing.We study the effects of the pressure ratio (varied from3 to 9.2) and the volume ratio (expressed as fill fractions) between the...

Autonomous Device for Application in Late-Phase Hemorrhagic Shock Prevention

Hemorrhagic shock (HS) is the leading cause of death for people with traumatic injuries. The onset of HS is correlated with marked changes in the plasma vasopressin levels and some studies indicate that administrating vasopressin in the bloodstream can help stabilize the situation. This situation calls naturally for the use of implantable devices for both the monitoring and treatment of HS. In ...

The Contact Surface in an Electromagnetic Shock Tube

An investigation of the luminosity structure, electron density, temperature, and arrival time of electrode material in the shock heated region of the plasma produced in a T-tube has disclosed that for the conditions studied the luminosity from this region originates primarily from gases that have passed through the contact surface. A plausible explanation for this mixing of discharge gases with...
