Abstract:

This communication deals with the convective flow of third grade nanofluid when the flow is induced by the stretching of a sheet in linear manner. Brownian motion and thermophoresis effects are considered in the transport phenomenon to describe the nanofluidics. Heat generation and absorption effects are also analyzed under the action of magnetic field. Similarity transforms are invoked for the conversion of system of partial differential equations into nonlinear coupled ordinary differential equations. Analytic solutions for the momentum, energy and mass fraction fields are computed and examined for the different physical parameters including the third grade parameter, heat source/sink parameter, nanofluidics parameters, Biot numbers etc. Numerical results for different sundry parameters are computed to present the different rheological effects. Comparison with an already published data is made in the limiting sense which shows a nice agreement between the two solutions.

Keywords: Convective cooling, heat generation/absorption, third grade nano fluid.
