Results and Discussion
The numerical solutions are tested under physiological flow conditions. The results of blood flow simulation show when the steady state of flow is achieved. The effects of parameters such as permeability \(K\) which depends on eq. (4), Reynolds number, and porosity and bend region were tested to investigate the effect of variable vessel geometry and on the fluid flow. the process of flow can be controlled under some conditions. The steady flow of blood through a porous medium in a vessel, the condition of the wall as a non-slip condition and considering the blood flow as an incompressible fluid were tested. Also, the artery is represented as a bent tube in 2D.
Fig.1 shows the details of the geometry which represent the length of vessel with the diameter and fluid regions maintained at every case. This representation carries the benchmarking for the mass and momentum equations. The results of the blood flow and the porous have been compared with those in the available literature[28]. Uniform flow profiles have applied at the inlet of the physical domain and hydrodynamic conditions at the outlet have been assumed.
