    Plasma-front propagation processes of 170 GHz millimeter-wave discharge were investigated under subcritical incident electric field intensity by using a one-dimensional model. The discharge structure was numerically reproduced at more than 0.2 MV/m by introducing the detailed chemical reaction and radiation transport processes into the conventional model. The results revealed that the propagation mechanism of the plasma front in the millimeter-wave discharge changes depending on the incident electric field intensity. At intensities greater than 1.4 MV/m, the plasma front propagated at supersonic speed, while forming a discrete structure, which has intervals of 1/4 wavelength of the millimeter wave. This structure was generated by electron-impact ionization and photoionization processes. At the intermediate intensities, the plasma front propagated continuously rather than discretely because the gas expansion increased the reduced electric field and induced electron-impact ionization. The dominant heating process at the plasma front was fast gas heating. At intensities less than 0.3 MV/m, the plasma front propagated continuously, but the dominant heating process changed to vibrational–translational relaxation. The discharge was maintained by thermal ionization and associative ionization. The simulation results were in good agreement with the past millimeter discharge experiments at this intensity.

    Abstract An improved model was proposed to reduce a computational cost for subcritical millimeter-wave discharge. The proposed model was able to reproduce the plasma-front propagation via radiation transport as similar to the conventional model, and the plasma-front propagation speed was in agreement with the previous simulation. An electron transport effect by neutral fluid advection, which has been introduced into the conventional model, does not affect the propagation speed. By using the presented model, a computational time was reduced by 35%, which was suitable for a multi-dimensional simulation in the future.

    Abstract A two-dimensional (2D) axisymmetric fluid modeling for plasma dynamics was coupled with an electromagnetic wave propagation to capture the electromagnetic wave and plasma structures on the microwave-driven in-tube accelerator (MITA) concept. The electromagnetic wave injected into a waveguide was focused on at the vehicle’s rear side through reflection processes by the front mirror and the waveguide. An overcritical plasma was created at the high-intensity electric field region because of enhancement of an electron-impact ionization. The incident microwave was reflected by the plasma with overcritical density and a standing wave was induced in front of the dense plasma because the reflected wave overlapped with the incident microwave. In addition to wave enhancement by standing process, the strong electric field region was obtained at edges of the overcritical plasma because of wave diffraction, which can affect a shock wave strength and thrust performance of the MITA.

    <p>A particle model of plasma was coupled with electromagnetic wave propagation to reproduce a filamentary structure and diffusive pattern in a microwave breakdown. The thrust performance of a microwave rocket was estimated by combining discharge calculation and computational fluid dynamics (CFD). An external magnetic field is applied to the discharge volume to improve thrust performance for low ambient pressure by combination of magnetic confinement and resonance heating technique. The magnetic field suppresses the propagation speed of the ionization front because the electron cannot cross the magnetic field at lower pressure, whereas propagation speed increases with decreased ambient pressure when no magnetic field is applied. The energy absorption rate increases when electron cyclotron resonance (ECR) occurs with the corresponding magnetic field, which improves the thrust performance of the microwave rocket.</p>

    To present a feasibility of high-altitude flight of a laser-propelled vehicle at supersonic speed, we have developed a flight simulator which has fluid-orbit coupling calculation module to reproduce impulsive flight reaction driven by blast waves. By high-power energy transmission through arrayed lasers together with the genetic algorithm (GA) controlled sub-laser, the supersonic flight is successfully achieved in the simulation for 32.5-g vehicle, while the angular offset should be suppressed as small as possible. Rather than translational position, controlling angular offsets by the GA operation is especially important to attain the km-order flight on the premise of the active control. Additionally, the vehicle weight, the vehicle size, and the input energy are scaled up to assess the stable flight of 10-kg vehicle. The active control technique has enough possibility to launch kg-order vehicle at supersonic regime with the optimized beaming strategy.

    Modeling of minute plasma formation is of great importance around electrodes of a plasma actuator(PA) utilizing dielectric barrier discharge(DBD)with a relatively low computational cost. Although electrons need some distance to acquire sufficient energy causing impact ionization, such a transient phenomenon cannot be described in a conventional fluid model because of local field approximation. In order to simulate appropriate discharge process in the DBD-PA, a hybrid code coupling with a particle model was constructed, which treats high-density region as the fluid model but high electric field region as the particle model. The hybrid simulation reproduced spreading of the high-density region from the exposed electrode for the positively biased case as well as the full-particle simulation.
