Heat and mass transfer of nanofluid flow in the presence of variable stream conditions

The effects of variable thickness, hydromagnetic flow, Brownian motion, heat generation, Thermophoresi, thickness, chemical reaction, porous medium, Lewis number and Prandtl number on heat and mass transfer characteristics and mechanical properties of a moving surface embedded into cooling medium consists of water with nano-particles are studied. The governing boundary layer equations are transformed to ordinary differential equations. These equations are solved numerically using fourth-fifth Runge-Kutta Fehlberg method with shooting technique. The velocity, temperature, and concentration profiles within the boundary layer are plotted and discussed in details for various values of all mentioned parameters, effect of the cooling medium and flatness on the mechanical properties of the surface are investigated to find the most effective parameters
