Abstract

Numerical calculations have been performed on liquid-metal magnetohydrodynamic flows through a rectangular channel in the magnetic field inlet region and magnetic field outlet region. The conservation equations of fluid mass and fluid momentum and the Poisson equation for electrical potential have been solved numerically. The numerical calculations have been carried out for Hartmann (Ha) numbers up to the order of 10 000 and a rectangular channel with electrically conducting channel walls. Attention is focused on pressure drops along the flow channel in the magnetic field inlet region and outlet region. The loss coefficients ζ can be represented by ζ=k(Ha2/Re)β for both the magnetic field inlet region and outlet region, where k is a coefficient, and Ha, Re, and β are the Hartmann number, the Reynolds number, and the channel aspect ratio, respectively. The coefficient k depends on the gradient of applied magnetic field in the magnetic field inlet region and outlet region. However, the coefficient k does not change with the Ha number, the Re number, the wall conductivity number, and the aspect ratio very much.

磁场入口区域和出口区域中液-液磁流体动流的数值计算

摘要

已经对在磁场入口区域和磁场出口区域中通过矩形通道的液态金属磁流体动力流进行了数值计算。数值求解了流体质量和流体动量的守恒方程以及电势的泊松方程。已经对高达10000的Hartmann(Ha)数和带有导电通道壁的矩形通道进行了数值计算。注意集中在沿着磁场入口区域和出口区域中的流动通道的压降。损耗系数ζ可以表示为ζ=ķH一种2个/[RËβ对于磁场入口区域和出口区域,其中k是系数,Ha,Re和β分别是哈特曼数,雷诺数和通道长宽比。系数k取决于磁场入口区域和出口区域中施加的磁场的梯度。然而,系数k不会随着Ha数,Re数,壁电导率数和纵横比而变化很大。
