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

Figure 8

Variation of wall shear stress with catheter radius ration different fluid models with $R_1=0.95\text{,}$$t={45}^{°}\text{,}$$\theta =0.1$ and $A={\alpha }_N=0.5$. One can observe that for all the fluid models, the wall shear stress decreases almost linearly with the increase of the catheter radius ratio. For a given set of values of the parameters, the wall shear stress of the two-fluid models is slightly higher than that of the single-fluid models. There is only a slight difference between the wall shear stresses of two-fluid H-B and Casson models. This graph exhibits the effects of catheterization on wall shear stress of the different fluid models for blood flow through catheterized arteries.
