A mathematically created model that represents the flow of blood by a stenotic blood vessel is used in the current investigation. The stenotic malady is arising due to the abnormal contraction of the flow passage in the arteries of human body. This contracting produces severe health problems and may minimize the flow of blood in arteries. The study of such mathematically constructed model facilitates us to examine such issues. The circular cylinder is taken with 0.3 m radius and 1.5 m length on the x-axis. The blood is passing through the intertwined stenosis artery. The developed model is assumed to be Newtonian. The segregated solver is applied on the developed model to solve the mass and momentum equations, which is based on the finite difference discretization. The findings indicate that, in comparison to all other regions of the vessel, the maximum narrowing regions of the stenosis eventuate most frequently, directly affecting the wall shear stress. The influence of narrowness on pressure and velocity are displayed in graphs. The pressure distribution of blood on the wall of the artery is also shown. Streamline for the velocity field is also examined.
