Shock Wave Velocity Modulation Effect due to the Interaction with the DC Discharged Field

Abstract

The relationship between the shock wave propagation velocity and the discharge power was investigated by applying the laser schrielen technique for the shock tube experiment at the shock Mach number of 2.17±0.03. The time interval of the shock wave arrival between the two laser beams was 160.5 μsec in the case without the discharged plasma. On the other hand, in the case with the discharged plasma, it was 157.8 μsec at 10.2 W and 149.2 μsec at 73.0 W, respectively. These results suggest that the shock wave propagation velocity can be accelerated with increasing the input power. This tendency agrees with the numerical simulation results, at least qualitatively.
