摘要
This paper investigates the effects of heat and mass transfer in the mixed convection flow of an Oldroyd-B fluid over a stretching surface with convective boundary conditions. Emphasis is given to the analysis of Soret and Dufour effects. Relevant problems are first formulated and then computed by homotopy analysis method (HAM). Soret and Dufour effects are considered. Velocity, temperature and concentration fields are given. In addition, the local Nusselt and Sherwood numbers are examined through numerical values. (C) 2016 The Authors. Published by Elsevier B.V.
