Abstract
An attempt has been made to explore the impact of Activation energy, Brownian motion, thermophoresis and the influence of changing viscosity and the current of Hall on hydro-magnetic free-convective flow, the transfer of energy and mass flow of a nanofluid across its stretched surface with Newtonian cooling and partial slip. The nonlinear in nature coupled mathematical equations regulating the flow were solved using the fifth-order Runge-Kutta-Fehlberg approach in conjunction with the firing technique. The impacts of different constants on the flow rates(f (,g), temperature((), and nano-concentration((), as well as the local skin-friction(Cfx,z) coefficient, local Nusselt(Nu) and Sherwood(Sh) numbers are graphed and analysed. It is found that ( upsurges with increase in Nb, Nt, h1 and reduces with (r and Rd. Nanoparticle concentration decay with Rd ,(r and convective heat transfer constant (h1). Higher the activation energy (E1) bigger ( and smaller the nanoparticle concentration. Nu enhances with Nt, diminishes with Nb, (r and h1. Sh smaller with E1 and upsurges with (.
