Computational Investigation on Flow of Nanofluid past an Exponentially Stretching Surface using VHPM

The theory of nanoliquids has revealed several fundamental properties, including a significant increase in thermal conductivity over the base fluid. In this study, we analyzed the nanoliquids two-dimensional laminar boundary layer flow over an exponentially stretching surface. Suitable variables are applied to simplify the nonlinear partial differential equations (PDEs) into ordinary differential equations (ODEs). The resulting equations are analytically solved by using the variational homotopy perturbation method (VPHM),and the graphical representation obtained with the help of the expressions for momentum, temperature, and concentration are evaluated for specific estimates of the dimensionless parameters, specifically the Lewis number(¿e), Brownian motion parameter (Nb), thermophoresis parameter (Nt), Prandtl number (Pr), of suction and injection parameters.
