Unsteady hydromagnetic chemically reacting mixed convection flow over a permeable stretching surface with slip and thermal radiation

The present investigation deals with unsteady hydromagnetic chemically reacting mixed convection flow of incompressible viscous fluid past a vertically moving permeable stretching sheet in the presence of suction/injection, heat source/absorption, thermal radiation, viscous dissipation and slip effects. The governing partial differential equations are reduced into a set of non-linear ordinary differential equations by suitable transformations. Keller box method is applied to solve the system of non-linear ordinary differential equations for which the implementation is made with the help of matlab. The important parameters in this study are: Prandtl number PrPr, Schmidt number ScSc, buoyancy force parameter λλ, radiation parameter NrNr, magnetic parameter MM, buoyancy forces ratio parameter NN, the unsteady parameter AA, suction/injection parameter ss, Eckert number EcEc, heat source/sink parameter QQ, chemical reaction parameter RR, velocity slip parameter svsv, temperature slip parameter stst and species concentration slip parameter smsm. Effects of these parameters on velocity, temperature and species concentration profile of the fluid are presented and analyzed graphically. Furthermore, numerical investigations have been made for the skin friction coefficient and surface heat and mass transfer rates for some of the parameters.
