| 内容記述 | The velocity variation of the shock wave in the crossed electromagnetic field was analyzed by the characteristic method, including the electrical conductivity variations due to the shock wave velocity, and assuming that the magnetic Reynolds number was very small and the Hall effect was negligible. The shock wave velocity attenuates slightly in the case than the electric field is controlled by an external resistance, and accelerates in the case that the electric field is controlled by an external battery. The effect of finite magnetic Reynolds number on the velocity variation is considered analytically. The effect is shown to be small. The experiments were done using a T-tube filled with Helium at an ambient pressure of 1 Torr. The measured values of the velocity variation of the shockwave in the electromagnetic field agree fairly well with the analytically obtained results. The voltage drop across the external resistance was measured. The results show that the Hall effect is negligible and the assumption that the electric field is uniform in the gas is correct. The intensity of the light emitted from the shocked gas in the electromagnetic field was measured. The intensity decreases in both cases of the attenuation and acceleration of the shock wave velocity. The intensity decreasing rate becomes large as the interaction of the shock wave with the electromagnetic field is large. These phenomena are explained qualitatively by the linearized characteristic method. But quantitatively the experimentally obtained results are much larger than the analytically obtained ones. | |||||||||
