【摘要】 讨论了用偶应力流体和双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。运用Ｓｔｏｋｅｓ的偶应力流体理论和Ｂｌｅｕｓｔｅｉｎ与Ｇｒｅｅｎ的双极流体理论，分别导出了轴向速度、径向速度、流量和壁面剪应力的解析式，并作数值计算，分析了管子锥度、偶应力参数和双极参数等对上述有关量的影响更多还原

【Abstract】 In 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 couple stress fluid and dipolar fluid. Analytical expressions for flow velocities (both axial and radial),volume flow rate and shear stress at wall are obtained using stokes’s couple stress fluid theory and Bleustein and Green’s dipolar fluid theory respectively. The numerical computations are performed and the effects of tapered angles and couple stress paramters and dipolar paramters respectively on those quantities above are analyzed.更多还原
