项目摘要

For the ignition and flame stabilization in combustors of scramjet engines, a method where an arc discharge is formed along the wall (direct arc discharge method) was proposed. In the direct arc discharge method, chemically active radicals produced by arc discharges can be used more effectively compared to the case of conventional plasma torches. Following results were obtained :1. The direct arc discharge method showed an excellent ability for the ignition and flame stabilization in supersonic flows, when the cathode is placed at upstream and the anode, at downstream flatly to the wall surface, and a carrier gas is injected through the gap of them.2. For the case with a wall step, a geometry, where the upstream surface is taken as cathode, and the downstream surface, as anode, and a carrier gas is injected through the gap at the bottom of the step, showed a successful result.3. Fuel-air mixtures showed an excellecn ability as carier gases.An experimental study was made to establish low power plasma jets (order of 100 W) with high exhaust gas temperature and high thermal efficiency. From detailed examination on the distance between cathode and anode, and the anode geometry, following results were obtained :1. Low power nitrogen plasma jets with a stable operation under atmospheric pressure were established with the combination of a high voltage power source and a high stabilizing resistor.2. An improvement in thermal efficiency and jet temperature was made by constructing the upstream part of the anode nozzle with boron-nitride and increasing the distance between the cathode and the anode.3. As for the anode geometry, the performance of the plasma jets becomes high with the decrease of throat length, but the optimum value of throat diameter changes for the maxinum thermal efficiency and the maximum plasma jet temperature.
针对超燃冲压发动机燃烧室点火和火焰稳定问题,提出了一种沿壁面沿着形成电弧放电的方法(直接电弧放电法)。在直接电弧放电方法中,与传统等离子体炬的情况相比,可以更有效地使用由电弧放电产生的化学活性自由基。获得了以下结果:1.当阴极置于壁面上游,阳极置于壁面下游,载气从阴极和阳极之间的差距注入时,直接电弧放电法在超声速气流中具有良好的点火和火焰稳定能力.对于有壁台阶的情况,将上游表面作为阴极,下游表面作为阳极,通过台阶底部的差距注入载气的几何结构显示出成功的结果.本文研究了低功率(100 W量级)、高排气温度、高热效率等离子体射流。通过对阴极与阳极之间的距离以及阳极几何形状的详细研究,得到以下结果:1。采用高压电源和高稳定电阻相结合的方法,建立了大气压下稳定运行的低功率氮等离子体射流.通过在阳极喷嘴的上游部分采用氮化硼材料,并增加阴阳极之间的距离,提高了热效率和射流温度.对于阳极几何形状,喉道长度越小,等离子体射流的性能越好,但喉道直径的最佳值对最大热效率和最高等离子体射流温度的影响不同。
