微极流体在带有小锥度圆管管道内的流动

讨论了用微极流体表示的血液在带有小锥度的刚性圆细管内的流动问题。在Ｃｏｎｄｉｆｆ和Ｄａｈｌｅｒ边界条件下，导出了轴向速度、径向速度、微转动速度、流量和壁面剪应力的解析式，并作数值计算，分析了管子的锥度和微极参数等对上述有关量的影响。

Flow of micropolar fluid through a smalltapered tube

n the paper,the steady flow of blood through a small rigid circular tube with small tapering angles is discussed and blood rheology is assumed to be described by a micropolar fluid' Analytical expressions for flow velocities (both axial and radial),microrotational velocity, volume flow rate and shear stress at wall are obtained under the boundary conditions proposed by Condiff and Dahler. The numerical computations are performed and the effects of tapered angles and micropolar paramters on those quantities above are analyzed.
