Numerical Studies on Gold-Water Nanofluid Flow with Activation Energy Past A Rotating Disk
Abstract The present study examines the steady incompressible gold-water chemically reacting nanofluid with rotating disk in presence of activation energy and Brownian diffusion. The model equations are treated with the Newton-based spectral quasilinearization method to ascertain the effects of different parameters of interest such as volume fraction and the Prandtl number on the velocity, temperature, concentration and heat and mass transfer rates. This method has been shown in the literature to be robust and rapidly convergent. The validity of the results is checked by comparing numerical results, in the limiting case, with published results in the literature. The study showed that the rate of flow, heat and mass transfer appreciate with increased volume fraction of the nanoparticles. Increasing the Prandtl was found to decrease temperature but increase concentration. A rise in the Schmidt number resulted in decreased temperature but did not have any appreciable effect on the concentration. Additionally, a lower temperature was predicted from a rise in activation energy while concentration was predicted to appreciate as a result of increased activation energy. The study has applications in the removal of contaminants in the beverages and waste water recovery industries..
