| Abstract: | In the paper, the flow characteristics of "the couple stress two-layer fluid" th-rough a rigid circular tube with mild stenosis are discussed and the analytical repre-sentations of the velocity, flux, impedance and maximal wall shear stress are obtained.The effects of the viscosity and thickness of the peripheral layer are considered, andthe numerical computations are carried out. The paper is the generlization of stenosisflow of the single-layer couple stress fluid and the two-layer Newtonian fluid. |

| Keywords: | couple stress fluid effects of stenosis Non-Newtonian fluid effects of peripheral layer. |
