Abstract

In this contemporary study, theoritical investigation of nanofluidic model is thought-out. Two-dimensional nanomaterials based mixed flow is considered here. Convective solar radiative heat transport properties have been investigated over a nonlinearly stretched wall in the presence of magneto-hydrodynamic (MHD), by innovative application of semi analytical “optimal homotopy asymptotic method (OHAM)”. OHAM does not require any discretization, linearization and small parameter assumption. OHAM describes extremely precise order solutions without the need of computing further higher order terms, therefore, fast convergence is observed. Nanofluidic governing model is transformed into system of ordinary differential equations (ODEs) by exploitation of similarity transformation. To study the significance of radiation parameter along with thermophoresis parameter, a semi analytical solver is applied to the transformed system. In this work, Brownian motion , influence of magnetic field, Lewis number, Prandtl number, Eckert number and Biot number have investigated on velocity, temperature and nanoparticle concentration profiles. The study provides sufficient number of graphical representations to demonstrate the inspiration of mentioned parameters.
