Pulsatile Flow of Two-Fluid Nonlinear Models for Blood Flow through Catheterized Arteries: A Comparative Study

Figure 1

Geometry of the catheterized artery modeled as two-fluid model. The flowing blood in the artery is modeled as a two-fluid model with the fluid (suspension of all the erythrocytes) in the core region being treated as nonNewtonian fluid and the fluid (plasma) in the peripheral layer region being treated as Newtonian fluid. Catheter is inserted into the artery coaxially. Since, the nonNewtonian fluid that we assume in the core region of the two-fluid model has yield stress, there is a plug-flow region which is bounded by the yield planes.
