Through this paper we investigated the heat and mass transfer effects of chemically reacting radiative Casson fluid flow over a slendering/flat stretching sheet in a slip flow regime with aligned magnetic field. This study is carried out under the influence of non-uniform heat source/sink. First we converted the governing equations of the flow into ordinary differential equations by making use of suitable similarity transformations. The resultant nonlinear differential equations are solved numerically using Runge-Kutta based shooting technique. Further, graphical representations have been given to study the effects of various physical parameters on velocity, temperature and concentration fields. Also numerical computation has been carried out to investigate the influence of various physical parameters involved on skin friction, heat and mass transfer coefficients. Through this investigation, it is observed that aligned angle, Casson parameter and velocity slip parameter have tendency to control the velocity field. Also heat transfer rate in the flow over a flat stretching sheet is higher than that of slendering stretching sheet. A good agreement of the present results with the existed literature has been observed. [ABSTRACT FROM AUTHOR]

This paper deals with the heat and mass transfer in unsteady flow of Powell-Eyring fluid past an inclined stretching sheet in the presence of radiation, non-uniform heat source/sink and chemical reaction with suction/injection effects. The governing equations are reduced into system of ordinary differential equations using similarity transformation and solved numerically using Runge-Kutta based shooting technique. Results display the influence of governing parameters on the flow, heat and mass transfer, friction factor, local Nusselt and Sherwood numbers. Comparisons are made with the existed studies. Present results have an excellent agreement with the existed studies. Results indicate that an increase in the chemical reaction parameter depreciates the friction factor, heat transfer rate and enhances the mass transfer rate. Dual solutions exist only for certain range of suction/injection parameters. [ABSTRACT FROM AUTHOR]

In this study we analyzed the magnetohydrodynamic forced convective flow of a nanofluid over a slendering stretching sheet in porous medium in presence of thermal radiation and slip effects. We presented dual solutions for no-slip and Navier slip conditions. Using self similarity transformation, the governing partial differential equations are transformed into nonlinear ordinary differential equations and solved numerically using BVP5C Matlab package. The effects of dimensionless governing parameters on velocity and temperature profiles of the flow are discussed with the help of graphs. Numerical computations are carried out and discussed for skin friction coefficient and local Nusselt number. We found an excellent agreement of the present results with the existed results under some special conditions. Results indicate that the dual solutions exist only for certain range of velocity slip parameter. It is alsofound that the heat transfer performance is high in presence of velocity slip effect.
