## Magnetic Field and Hall Currents Influences on Blood Flow Through a Stenotic Artery

• 摘要: 对一个水平向不对称、竖直向对称，带有轻微狭窄的动脉，提出了血液磁流体动力学流动的微极模型．为了估计狭窄形状的影响，几何上加以适当地考虑，通过选取不同的参数（称为形状参数），很方便地改变水平向的狭窄情况．在不同形状参数、Hartmann数和Hall参数下，计算了流动参数，例如流速、流动阻力（阻力阻抗）、狭窄区域血管壁面剪应力分布以及狭窄最大凸起高度位置处（狭窄喉部）的壁面剪应力大小．结果表明，流动阻力随着确定狭窄情况参数值和Hall参数值的增大而减小，并随着Hartmann数的增大而增大．对任意给定的Hartmann数和Hall参数，血管壁面剪应力和血管狭窄部位凸起最大高度处的管壁剪应力，具有与流动阻力相反的特征．最后，给出了Hartmann数和Hall参数对水平速度的影响．
