Mixed Convection flow of Chemically reacting Couple Stress fluid in an annulus with Soret and Dufour effects

Abstract

In this paper, mixed convection flow of couple stress fluid in circular annulus is studied. First order chemical reaction, Soret and Dufour effects are taken into consideration. The governing partial differential equations are transformed into a system of ordinary differential equations and solved by Homotopy Analysis Method (HAM). The effects of Soret number, Dufour number, chemical reaction parameter and couple stress parameter on the dimensionless velocity, temperature and concentration are analyzed graphically.
