• Maxwell and Oldroyd-B fluid

A two dimensional (2D) boundary layer two-phase MHD (magneto hydrodynamics) flow of Maxwell and Oldroyd-B fluid over a stretching sheet has been explored. Heat and mass transfer phenomena is inspected through Non-linear radiation, viscous dissipation, joule heating, Soret (thermo-diffusion) and Dufour (diffusion-thermo) Impact. The boundary layer governing differential equations are modelled and transformed to a system of ODE'S with the aid of similarity transformations. The final controlled equations along boundary restrictions are resolved numerically by Runge-Kutta Felhberg method. The graphical analysis has been emphasized for the fluid and dust phase velocity, temperature and concentration fields to the influence of sundry dynamical flow quantities. Furthermore, for authentication of the present computation, the achieved results are distinguished with earlier research works in specific cases and marvellous agreement has been noted. The outcomes conveyed here manifest that velocity and boundary layer thickness escalate with boost up the values of K-1. Velocity and boundary layer thickness declines with boost up the values of M. Opposite trend is seen in temperature and concentration profiles. The specific heat ratio parameter gamma enhances the temperature profile declines. Boost up the values of Soret number Sr temperature profile declines and concentration profile enhances. Skin friction factor declines with increasing values beta(upsilon) verses M.
