Couple Stress Hybrid Nanofluid Flow through a Converging-Diverging Channel

Abstract

This research work is aimed at scrutinizing the mathematical model for the hybrid nanofluid flow in a converging and diverging channel. Titanium dioxide and silver are considered solid nanoparticles while blood is considered as a base solvent. The couple stress fluid model is essentially used to describe the blood flow. The radiation terminology is also included in the energy equation for the sustainability of drug delivery. The aim is to link the recent study with the applications of drug delivery. It is well-known from the available literature that the combination of TiO2 with any other metal can vanish more cancer cells than TiO2 separately. Governing equations are altered into the system of nonlinear coupled equations the similarity variables. The Homotopy Analysis Method (HAM) analytical approach is applied to obtain the preferred solution. The influence of the modeled parameters has been calculated and displayed. The confrontation to wall shear stress and hybrid nanofluid flow growth as the couple stress parameter rises which improves the stability of the base fluid (blood). The percentage (%) increase in the heat transfer rate with the variation of nanoparticle volume fraction is also calculated numerically and discussed.
