The present work deals with the flow of blood through a bell shaped stenosis assuming that the flowing flood is represented by a macroscopic two-phase model (i.e., a suspension of erythrocytes in plasma). The coupled differential equations describing the flow of fluid (plasma) and the particle (red cell) phases have been solved and the expressions for the flow characteristics, namely, the impedance, the wall shear stress in the stenotic region, the shear stress at the stenosis throat have been derived. Results obtained in the paper have been discussed graphically in brief.
