Abstract

This paper considers the MHD boundary layer flow and heat transfer characteristics of FeCasson-based nanofluid over an exponentially stretching/shrinking surface, including heat source/sink and Newtonian heating effects. In this regard, to develop the system of the governing equations, the one phase model named as Tiwari and Das model is considered with iron nanoparticles. The non-linear governing partial differential equations (PDEs) are first changed into the system of ordinary differential equations (ODEs) using suitable similarity transformations. Later on, the ODEs are numerically solved using bvp4c in Matlab software. Effects of certain physical parameters on skin friction coefficient and the local Nusselt number are illustrated graphically. Furthermore, the study examines velocity and temperature profiles to observe the influence of various physical parameters, including Casson, magnetic, suction, radiation, Newtonian heating, heat source/sink, and nanoparticle volume fractions. The findings reveal that an increase in Casson, magnetic, suction, and nanoparticle volume fractions leads to a decrease in velocity profiles for both stretching and shrinking surfaces. Additionally, the temperature profile decreases with an increase in Prandtl number and the suction parameter for both stretching and shrinking cases, while it increases with an increase in magnetic, radiation, and nanoparticle volume fractions.
