Title Parametric Investigation of Entropy Production in Jeffrey Nanofluid Past an exponential Stretchable Surface with Convective Conditions

Author(s) Umm-e-Zainab Saeed

Abstract This study presents a parametric investigation of entropy production in a Jeffrey nanofluid flow over an exponentially stretchable surface, considering convective boundary conditions. Under the boundary layer and Rosseland's approximations, a mathematical model of the flow problem under consideration is developed. Utilizing the Jeffrey fluid model, which characterizes the non-Newtonian behavior of the nanofluid, the governing nonlinear PDEs are transformed into a set of ODEs through appropriate similarity transformations. Then the ODEs are solved by applying homotopy analysis method. The effects of physical parameters on dimensionless temperature, concentration, and velocity are demonstrated and examined. Additionally, the study investigates how different parameters affect the system's average entropy generation number, skin friction, Sherwood number, Nusselt number, and entropy generation number. A Mathematica program was used to make graphs that show the results of all physical parameters.
