简化理论研究液态包层通道插件流体MHD效应

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。

A simplified theoretical study on MHD flow with FCI in liquid metal blanket system

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.
