Abstract

Quasi three-dimensional analysis is made to estimate effects of applied current parallel to magnetic field on the characteristics of nonequilibrium Faraday MHD generator. Potassium-seeded argon plasma at 1500 K and 10 atm is assumed. Resistive power-extraction electrode is taken into account to reduce the current concentration phenomena occurring at electrode edges. The applied current parallel to magnetic field enlarges the stable region free from ionization instability. The net output power exceeds the power obtained for the case of no applied current in the limited ranges of applied current and Hall parameter. The resistive power-extraction electrode is useful to successfully prevent the applied current from short-circuiting along the electrode surface.

用电流并联磁场改善非平衡MHD发电机特性
通过准三维分析,估计了平行于磁场的外加电流对非平衡法拉第MHD发电机特性的影响。假设在1500 K和10 atm下的钾种子氩等离子体。为了减少电极边缘的电流集中现象,采用了电阻式抽电电极。与磁场平行施加的电流扩大了不受电离不稳定性影响的稳定区域。净输出功率超过在施加电流和霍尔参数的有限范围内没有施加电流的情况下获得的功率。电阻式功率提取电极可有效防止施加电流沿电极表面短路。
