摘要：

基于先前的普通管道中的MHD效应的实验结果和质量守恒定律(或液态流体不可压缩原理)、洛仑磁力定律和电荷守恒定律，再利用有源网络等效方法，发展出一种简化而有效的分析带通道插件(FCI)管道的磁流体动力学(MHD)效应的方法。简化理论预测结果表明：采用FCI可有效地降低MHD压降；FCI的电导率存在一个临界值时，当大于这个值时，中心区流速将小于边界区流速；管道结构、FCI电导率、液态金属种类等存在着一个最佳组合参数，能最有效地减少MHD压降。

Abstract:

Based on the previous MHD duct flow experiments, the law of mass conservation, the law of charge conservation and the Lorentz force as well as the principle of equivalent circuit, a simplified theoretical method to analysis MHD effect of duct with FCI is developed. The result shows that FCI can reduce MHD pressure drop efficiently; there is a critical electric-conductivity that when the FCI electric-conductivity is higher than this value the velocity in the core region will be lower than that at the boundary; there is also an optimized parameter-combination of duct geometry, FCI electric-conductivity and liquid-metal material for the MHD pressure drop reduced efficiently.
