Influence of Magneto Hydro Dynamics (MHD) Nonlinear Radiation on Micropolar Nanofluid Flow Over a Stretching Surface: Revised Buongiorno’s Nanofluid Model

Abstract

A mathematical model is proposed to explore MHD micropolar nanofluid flow across a permeable stretching plane under non-linear radiation. Implication of heat generation with activation energy, Neild’s condition and Second order momentum slip of micropolar nanoparticles on the sheet is an additional features in respect novelty. For nanofluid, Buongiorno’s model, which includes thermophoresis and Brownian motion, is assumed. With the aid of new similarity transformations, the governing PDEs are reduced into nonlinear ODEs. Later, these reduced eq’s are numerically solved using 4th order Range–Kutta method adopting shooting technique and coded in MATLAB. To validate the imparted findings, a comparison with previously published limited case studies is included. The salient fluid flow characteristics of three distributions are expressed figuratively for multifarious selected germane parameters. Applications of the study arise in materials processing.
