Radiative heat flux effect in flow of Maxwell nanofluid over a spiraling disk with chemically reaction

In this paper, thin film flow of Maxwell nanofluid caused by a radially stretching and rotating disk is investigated by employing the revised Buongiorno's model in the presence of uniform magnetic field. The impact of non-linear thermal radiations is studied on heat transfer characteristics. The nanofluid model utilized in the present study employs the features of Brownian motion and thermophoresis together with condition of zero normal flux of nanoparticles. The reduced system of governing equations have been solved through a numerical technique namely bvp4c. The impact of physical parameters is studied on fluid velocity, temperature, and concentration profiles. The obtained results reveal that both the film thickness and velocity components decrease with magnetic parameter. Further, the surface heat flux diminishes with the viscosity and thermophoresis parameters. Moreover, Brownian motion and chemical reaction parameters play a significant role in reducing the nanoparticles concentration. (C) 2019 Elsevier B.V. All rights reserved.
