Keller box numerical analysis of power-law rotating disk for nanofluid flow with chemical reaction

Abstract

The present study concentrates on the numerical treatment of the flow of the 3D boundary layer on a nanofluid above a rotating disk. The chemical reaction and generation or absorption of heat has been incorporated. According to published literature nanofluids play a key role in the improvement of thermal conductivity. More significantly, nanofluids are utilized in medical field, engineering and in industry. In addition, this attempt will be helpful for the researcher to analyze energy and mass transport rates for nanofluids. Further, in this study, Brownian motion and thermophoretic impacts are taken into account. The governing flow equations are converted to ODEs (ordinary differential equations) via suitable similarity transformations. The numerical outcomes are recovered with the utilization of well know technique KBM (Keller box method). The velocity and energy transport rates are discussed graphically for power law index, thermophorsis, and Brownian motion. Graphs present the temperature and concentration distribution increase for the upturn of thermophoretic impacts. While, temperature and concentration distribution show decreasing behavior for Brownian movement factor. In addition, increment in power index factor diminishes the temperature distribution and concentration of the liquid.
