A mathematical model of two-layered pulsatile blood flow through stenosed arteries demonstrated that slip velocity and body acceleration increase velocity and flow rate.
A mathematical model demonstrates that slip velocity and body acceleration increase blood flow velocity and flow rate in stenosed arteries.
In the present paper a two fluid model for pulsatile blood flow through stenosed artery has been developed. The model consists of a core region of suspension of all the erythrocytes assumed to be a Bingham plastic fluid and a peripheral layer of plasma as Newtonian fluid. The analytic expressions for blood flow characteristics namely velocity, wall shear stress, flow rate, plug core radius and effective viscosity are obtained by using perturbation method. The effects of body acceleration and slip velocity have been discussed. We have shown the variation of flow variables with the different parameters and discussed with the help of graph. It is observed that the velocity and flow rate increases but effective viscosity decreases, due to a slip velocity. Body acceleration further enhances the velocity and flow rate.
Siddiqui et al. (Thu,) conducted a other in Stenosed arteries. Two fluid model for pulsatile blood flow was evaluated on Blood flow characteristics (velocity, wall shear stress, flow rate, plug core radius, effective viscosity). A mathematical model of two-layered pulsatile blood flow through stenosed arteries demonstrated that slip velocity and body acceleration increase velocity and flow rate.
