Numerical method
The numerical modelling for the determination of distributions of hydrodynamics of blood flow inside vessel as a porous model has been described. This section discusses the numerical modelling aspect resulting according to the geometry.
Simulations have been performed using the Finite Volume Method (FVM). Time step and grid size have been used until convergence is reached. The numerical simulations estimate the impact of the leading parameters such as geometry, permeability, and porosity.
To investigate the effect of vessel geometry on the blood flow, the vessel with \(90^{o}\) bend was chosen. Figure (1) shows the two-dimensional representation of the blood vessel and geometric parameters for the simulations. The boundary conditions and flow parameters were the same as described previously. A fine mesh setting is used for the domains. Aiming to a mesh independent study, a mesh with 2.1 million nodes with the maximum element size of 5x10-4 µm has been used (Figure (1)). The Convergence residuals criteria have set to 1 × 10-7 for all flow variables.
