Introduction: In this research the behavior of coronary arteries has been studied with symmetric and asymmetric consecutive stenosis, and grafted vessels. Methods: The incompressible Navier-Stokes and energy equations were discretized with second-order upwind method. Assumptions such as Newtonian fluid, wall rigidity and steady-flow were used. Results: All the calculations showed the same results with Newtonians and non-Newtonian fluids. It was found that the possibility of stenosis be reduced by increasing the graft angle. However, there...
