ABSTRACT

The effect of double diffusion on mixed convection of a viscous incompressible in an axisymmetric stagnation flow of nanofluid past a vertical cylinder with constant or variable thermal wall condition is analyzed. The model used for the nanofluid incorporates the effects of Brownian motion and thermophoresis. The governing equations are transformed into dimensionless form using the stream function and suitable variables. The transformed equations are then solved numerically using the Runge-Kutta numerical integration procedure in conjunction with the shooting technique. A parametric study of the physical parameters is conducted, and a representative set of numerical results for the velocity, temperature, and nanoparticles volume fraction profiles as well as the local friction factor, and the local Nusselt and Sherwood numbers, are illustrated graphically to show interesting features of the solutions.
