摘要

建立了微极流通过多孔扁球体的数学模型。椭球体的渗透率为k，假定离椭球体较远且沿椭球体对称轴流速均匀。颗粒内部的流动遵循孔隙度的DarcyBrinkman定律，而颗粒外部的流体则遵循A.C. Eringen微极流动理论。阻力由渗透率参数η和耦合数N的变化值决定。同时，对微极参数m进行了数值研究。

Creeping Micropolar Flow past a Porous Oblate Spheroid

A mathematical model for the creeping micropolar flow past a porous oblate spheroidal body is presented. The oblate spheroidal body possesses permeability k and uniform stream velocity is assumed far away from the body and along its axis of symmetry. The flow inside the particle obeys the DarcyBrinkman laws of porosity and the fluid outside is governed by the A.C. Eringen micropolar flow theory. Drag is determined with varying values of the permeability parameter η and the coupling number N . Also, the micropolar parameter m is studied numerically.
