The flow of Casson fluid in contact with Jeffery fluid in a tube with a small diameter is concentrated in this paper. Casson fluid is considered in the central region and Jeffery fluid in the outer region. The governing equations are solved analytically and obtained expressions for velocity, flux, effective viscosity, central hematocrit, and mean hematocrit in dimensional form. The effect of many physical parameters on velocity, flux, effective viscosity, central hematocrit, and mean hematocrit is observed through graphs. Central hematocrit increases with an increase in yield stress and hematocrit and means hematocrit decreases with an increase in yield stress and hematocrit. The paper finds its applications in the flow of blood in narrow arteries, vines, and capillaries. The problem warrants further study on the flow of non-Newtonian two-fluid flows in a narrow tube.

血液在狭窄管子上接触cri药液的卡森液流的影响

本文将卡森流体与Jeffery流体在小直径管中的流动集中。在中心区域考虑了卡森流体，在外部区域考虑了杰弗里流体。通过解析求解控制方程，并以速度形式获得速度，通量，有效粘度，中心血细胞比容和平均血细胞比容的表达式。通过图表观察许多物理参数对速度，通量，有效粘度，中心血细胞比容和平均血细胞比容的影响。中央血细胞比容随屈服压力和血细胞比容的增加而增加，意味着血细胞比容随屈服压力和血细胞比容的增加而降低。本文在狭窄的动脉，藤蔓和毛细血管的血液流动中发现了其应用。
