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

Figure 6

Variation of flow rate with yield stress for different two-fluid models with $R_1=0.95\text{,}$$t=45$°, $A=k=\alpha ={\alpha }_H={\alpha }_C=0.5$. It is seen that for increasing values of the yield stress $\theta$, the flow rate decreases linearly for the two-fluid H-B model and it decreases very slowly for the two-fluid Casson model. For a given set of values of the parameters, the flow rate decreases marginally with the increase of the power-law index n. The flow rate of the two-fluid H-B model is significantly higher than that of the two-fluid Casson model.
