This study investigates the hemodynamics of nanofluid in a stenotic bifurcated artery, modeling blood as a couple stress fluid and solving coupled non-linear equations using the homotopy perturbation method. It is found that couple stress nanofluid exhibits high wall shear stress at the location of maximum constriction.
In this article, we are exploring the hemodynamics of nanofluid, flowing through a bifurcated artery with atherosclerosis in the presence of a catheter. For treating obstruction in the artery, one can use the catheter whose outer surface is carrying the drug coated with nano-particles. The resultant solvent is considered as blood nano-fluid. Blood being a complex fluid, is modeled by couple stress fluid. In the presence of nano-particles, the temperature and the concentration distribution are understood in a bifurcated stenotic artery. The concluded mathematical model is governed by coupled non-linear equations, and are solved by using the homotopy perturbation method. Consequently, we have explored is the effects of fluid and the embedded geometric parameters on the hemodynamics characteristics. It is also realized that high wall shear stress exists for couple stress nano-fluid when compared to Newtonian nanofluid. which is computed at a location corresponding to maximum constriction (z = 12.5) of the artery.
