Abstract: Cerebral transient ischemic attacks and strokes are usually related to embolic occlusion of cerebral arteries, which originates from the heart. It causes due to the hemodynamic impact of cardiac function on the flow in the brain-supplying arteries, i.e., carotid arteries. The ischemic attacks and strokes can be minimized by increasing cardiac output and reducing the resistance which decreases the arterial pressure. The nonlinear unsteady flow phenomenon is governed by the Navier-Stokes equations. These equations with appropriate boundary conditions describe the present biomechanical problem and are solved numerically by adopting finite element technique. The respective profiles of the cardiac output, flow rate, arterial pressure and flow velocity in terms of pressure waveform as well are obtained. The obtained results are compared with the available experimental observations.
