Pressure Measurements in a Magnetically Driven Shock Tube

摘要

Measurements of total pressure and static pressure were taken in a magnetically driven shock tube at an Alfvén Mach number of M1≈0.66 in air at an initial pressure range of 50–200 μHg. Total pressure measurements ranged from 0.3–0.8 of the Newtonian pressure based on an equilibrium real gas density ratio. A small separation between the shock and drive current sheet was detected over the range of initial pressures, but was not always repeatable. The static pressure was measured and found to be approximately equal to the drive magnetic pressure.
