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

Figure 5

Variation of flow rate in a time cycle for different fluid models with $R_1=0.95\text{,}$$t={45}^{°}\text{,}$$A=k=\alpha ={\alpha }_H={\alpha }_C=0.5$ and $\theta =0.1$. It is found that for all the fluid models, the flow rate is maximum at 90° and it is minimum at 270°. At any instant of time t, the flow rate of the two-fluid H-B model is significantly higher than that of the two-fluid Casson model. A similar behavior is seen for the single-fluid H-B and Casson models. The flow rate of the two-fluid H-B model is significantly higher than that of the single-fluid H-B model.
