摘要:
给出配置了环形线电极的单极机中的磁流体力学解析解.由于问题是线性的, 求解可简化为基本解的叠加,可利用单极机在两个区域中的基本解的衔接来求得解析解.讨论了基本解的性质. 利用非完全电极可改善Hartmann边界层、增加装置中的质量流量. 应用基本解讨论了连续电极的单极机.
Abstract:Themagnetohydrodynamic flow in a homopolar device with annular linearelectrodes is studied analytically．As the problem is linear, thesolution may be reduced to the summation of elementary solutionsobtained by matching the local solutions in two regions or thehomopolar device. The flow features of the elementary solutionsare discussed. The structure of incomplete electrodes can improvethe Hartmann boundary layer and increase the mass flux of thehomopolar. The elementary solutions are also applied to thediscussion of a homopolar device with continuous electrodes．
