Abstract
The main purpose of this investigation is to present the effects of Dufour and Soret on MHD convection of an Oldroyd-B liquid over a stretchy sheet with Cattanao-Christov heat flux model in the appearance of radiation and chemical reaction. The governing systems of non-linear PDE's are reconstructed into non-linear ODE' s. The resulting intricate non-linear boundary value problem is solutes through homotopy analysis method. The influence of various physical parameters on velocity, concentration, temperature profiles and dimensionless version of local skin friction, local mass and heat transfer rates are discussed through graphs.
