Abstract:
The objective of present research work is to establish the non-Newtonian nanofluid flow and heat transfer along a stretching surface. Stagnation point flow of Prandtl nanofluid is purposed over a convective surface where zero normal flux of nanoparticles is considered to disperse the particle away from the surface. Physical problem is governed by mathematical model which consists of continuity, momentum, energy and concentration equations which are adapt to non-linear ordinary differential equations using transformation of variables. Numerical computational is implemented for coupled nonlinear equations using finite difference method (FDM) to analyze the flow and heat transfer characteristics under the influence of various physical parameters namely: Prandtl fluid parameter, elastic parameter, magnetic parameter, stagnation parameter, Prandtl number, Brownian motion parameter, thermophoresis parameter, Lewis number, stretching parameter, and Biot number. Obtained results describe the effects of significant parameters on temperature and nanoparticle volume concentration due to zero flux and convective boundary condition. It is found that due to zero flux, concentration of nanoparticles disperse at the surface within the boundary layer region.
