Figure 4: Velocity distribution of blood flow for diameter 100 µm different permeability. Variable porosity \(\varepsilon\) = 0.5,1. Variable Re (0.1, 1, 5).
The variation of flow rate for different values of the permeability factor in the cases of constant porosity (\(\varepsilon\) =0.5, 1) is shown in Figure 4. In both the cases of porosity, the flow rate increases rapidly as diameter increases from100 to500 µm. It is also observed that the variation of pressure gradually increases as the diameter of the vessel increases in the cases of constant porosity (\(\varepsilon\) =0.5, 1). Furthermore, the pressure is increased when the porosity factor increases at constant diameter as is shown in Figures 5(a, b).
