Abstract
The contemporaneous research was conducted to evaluate the attribute of blood flow and degree of obstruction generated in the arteries pathway through different geometries. Flow of blood via the stenosed afflicted arteries is taken into account in this work. The viscous, unsteady, incompressible and laminar, blood plunge into the artery with a speed of 0.049 m s−1. Partial differential equations were demonstrated for the current problem. Time dependent direct solver was used to obtain the solution. Finite element discretization method (FDM) is used to obtain the solution. The research was accomplished by using advanced computational fluid dynamics (CFD) software. The blood flow behavior was investigated in order to determine velocity, pressure, and temperature changes caused by an arterial stenosis. It was discovered that the shape of the stenosis has a crucial impact on the velocity, total pressure reduction and temperature over the arterial constriction zone. Graphs are plotted to illustrate the solutions. Results shows that the trapezoidal and elliptical stenosis had the greatest pressure decrease, followed by the triangular stenosis. These findings will be extremely beneficial in the treatment of stenotic arteries.
