MAGNETIZED NANO FLUID FLOW OVER A STRETCHING SHEET DUE TO CHEMICAL REACTION AND NON-LINEAR THERMAL RADIATION WITH NAVIER SLIP AND CONVECTIVE HEATING

This study investigates the heat and mass transfer due to nano fluid flow over a vertical porous stretching sheet. The transport equations employed in the analysis include the effect of thermal radiation and chemical reaction. Brownian motion and Thermophoresis effect with the slip and convective boundary conditions are also taken into account. Similarity transformation is used to convert the governing nonlinear equations and their related boundary conditions into coupled higher order ordinary differential equations. The differential equations are solved numerically using Runge- Kutta fourth order method with shooting technique. The evaluations are carried out for velocity, temperature and concentration distribution as well as for the local Nusselt number and Sherwood number. It is witnessed that the velocity of the fluid decreases for boosting values of the magnetic and suction parameters. Due to increment in magnetic field, temperature and concentration increases. It is found that velocity increases when permeability of the porous medium and thermal radiation parameter increases. Temperature is found in increasing mode with thermal radiation coefficient whereas found in decreasing mode with permeability of the porous medium and suction parameter. Concentration decreases with increase of suction parameter and rate of chemical reaction parameter. It is found that local Nusselt number and Sherwood number both are increasing function of prandtl number, stretching parameter and suction parameter. The presented model supports the results of previously published papers in the literature.
