Mixed convection flow of viscoelastic nanofluid over a stretching cylinder

Abstract

Boundary layer flow of viscoelastic fluid over a stretching cylinder is examined in this paper. Brownian motion and thermophoresis effects are studied in the presence of mixed convection. The governing boundary layer partial differential equations are reduced into ordinary differential equations through suitable transformations. The homotopic series solutions have been developed. Influence of physical parameters on the velocity, temperature and concentration fields are analyzed graphically. Local Nusselt and Sherwood numbers are computed numerically for different values of parameters. Physical interpretation is discussed.
