项目摘要
This research aims to clarify an electromagnetic acceleration mechanism of plasma flow and to control Mach number of the plasma flow using a magnetic nozzle for optimization of the plasma acceleration. Especially, we have directly observed the electromagnetic force (Lorentz force) accelerating the plasma in the Laval-type magnetic nozzle and compared it with the flow velocity measurement. We investigated in detail the formation of the Lorentz force in various magnetic field configurations and effects on the acceleration. The results are summarized as follows.1.The thermal energy of the ion was converted into the flow energy by passing through the Laval type magnetic nozzle at the muzzle of Magneto-Plasma-Dynamic arcjet (MPDA). The ion Mach number of the plasma attains to more than unity and the supersonic plasma flow was obtained.2.Spatial profiles of the several plasma parameters, flow velocity, ion temperature and Mach number of the plasma, were consistent with the theoretical results derived from the one-dimensional isentropic flow model.3.It was experimentally clarified that the magnetic field in the plasma flow became weak caused by the diamagnetic effect and the converging magnetic field was spontaneously formed near the MPDA. The Lorenz force by the azimuthal current and the inward magnetic field decelerated ions in the plasma.4.Adding a strong diverging magnetic field improved the deformation of the magnetic field and changes the deceleration force to acceleration force, which resulted in a large increase of plasma flow velocity.As a result, we have shown that the electromagnetic force acting on the plasma flow could be controlled directly by shaping the external magnetic field, and clarified the plasma acceleration mechanism and its control methods.
这项研究旨在阐明血浆流的电磁加速度机理,并使用磁喷嘴来控制等离子体加速度的血浆流量的马赫数。特别是,我们直接观察到电磁力(Lorentz力)加速了Laval型磁性喷嘴中的血浆,并将其与流速测量进行了比较。我们详细研究了洛伦兹力在各种磁场构型中的形成以及对加速度的影响。结果总结如下。1。通过在磁磁力 - 动力弧(MPDA)的枪口上穿过Laval型磁性喷嘴,将离子的热能转化为流量。血浆的离子马赫数比统一更重要,并且获得了超音速等离子流。2。几个等离子体参数的空间特征,流速,离子温度和等离子体的马赫数与从理论结果一致。一维等体流量模型。3。它在实验上澄清了血浆流中的磁场由于磁管效应而引起的弱,并且收敛的磁场在MPDA附近自发形成。方位角电流的洛伦兹力和血浆中的内向磁场减速。4。添加强大的磁场改善了磁场的变形,并将减速力变成加速力,从而导致了血浆的大量增加由于结果,我们已经表明,作用在等离子体流上的电磁力可以通过塑造外部磁场直接控制,并阐明了血浆加速度机制及其控制方法。
