Abstract

Simultaneous effects of non-Newtonian and curvature on unsteady nano-fluid flow through overlapping stenosed channel have been investigated in this letter. In this numerical investigation, a mathematical formulation is developed in order to analyze the influence of blood shear thinning/thickening effects on the rheology of the nano-fluid within curved channel which is not explored yet. Moreover, the numerical solutions for temperature, velocity and concentration equations are obtained and discussed its hemodynamic effects due to the curvature of the stenosed channel. Graphical results are designed in such way to comprehend its complete theoretical assessment. The graphical streamlines would give pictorial overview of the nano-fluid flow through stenosed cress section under the influence of the emerging parameters variation. The pattern of the results instigates the change in the size of trapping bolus for different value of the specified parameters; these will give the pictorial understanding to the general readers. Apart from this, the obtained numerical results are also validated.
