Abstract

In this paper, steady two-dimensional magnetohydrodynamics mixed convective flow of non-Newtonian power law nanofluid with the presence of heat generation/absorption and chemical reaction effects is investigated. The nanofluid incorporates the effects of Brownian motion and thermophoresis using Buongiorno’s model. The flow is studied in a cavity with a moving top wall and contains isothermal solid circular cylinder at the center. The governing dimensional equations in a vector form are transformed into non-dimensional form. Then, the dimensionless equations are solved numerically by finite element method (FEM) using automated solution technique which is FEniCS. The influence of various parameters such as Richardson number, power-law index, magnetic field, heat generation/absorption, chemical reaction and size of solid circular cylinder on velocity, temperature, and concentration profiles are presented and discussed in this study. The results show that increasing Richardson number and power-law index has enhanced the velocity and the temperature profiles (left side of cavity). Meanwhile, both profiles reduce when the magnetic parameter and the size of solid circular cylinder are added. The temperature profile is increased with the rising of heat generation/absorption parameter. Besides that, declining trend is observed on the concentration profile with increasing chemical reaction parameter.
