Analysis of flow parameters in blood flow through mild stenosis

A buildup of plaque that contracts arteries and decreases blood flow to the heart causes chest pain, difficulties in breathing, or another coronary artery disease, medically called stenosis puts our lives at risk. We have used Navier-Stokes equations a cylindrical polar coordinate system study this problem by considering is steady, axially symmetrical, fully developed, laminar. Flow parameters like velocity profile, pressure drop, shear stress, volumetric rate stenosed regions are analyzed after getting analytical solutions. focused know effect thickness different viscosity coefficient on behavior.
