Abstract


Present study offered for the laminar free convection boundary layer flow of Eyring-powell non-Newtonian fluid past a horizontal circular cylinder in the occurrence of magnetic effect, and Soret, Dufour effects. The cylinder surface is maintained at non-uniform surface temperature. The boundary layer conservation equations, transformed into non-dimensional form via appropriate non-similarity variables, and the emerging boundary value problem is solved computationally with the second order accurate implicit Keller-Box finite difference scheme. Evaluation on velocity, temperature and concentration are illustrated graphically. Skin friction and Nusselt number are presented tabular form.


Keywords
