Assessment of heat and mass transfer characteristics in Poiseuille flow of non-Newtonian nanofluid in a porous channel with convectively heated lower wall

Abstract

This research aims to develop a mathematical model based on the flow of Eyring-Powell fluid with an assessment of combined heat and mass transfer features confined by a horizontal channel. The lower wall of the horizontal channel has been assumed to be convectively heated. Following the fundamental laws and associated stress tensor of Eyring-Powell nanofluid, the governing equations are developed. The formulated flow expressions are altered into non-dimensional forms with appliances of normalized variables. The analytical procedure based on the perturbation technique is employed to access the solution. The physical exploration of interesting quantities govern to the flow is addressed. The numerical data is presented based on the assessment of the heat and mass transfer phenomenon. A comprehensive discussion regarding the physical insight of all flow variables has been presented.
