Thermal study on the performance of Joule heating and Sour-Dufour influence on nonlinear mixed convection radiative flow of Carreau nanofluid

Abstract

BackgroundWith the progress of solar energy application and nano-technology, nanofluid heat assortment has fascinated noteworthy consideration. The solar plasmatic nano-fluids with substantial limited surface Plasmon resonance influence have shown greater performances in thermo-physical aspects, ophthalmic stuff, and photo-thermal exchange efficacy. The theory of nanofluid has induced broad attention from scientists around the globe because of their unique thermo-physical possessions and various prospective benefits and uses in essential arenas for example, atmosphere, energy, microchip technology and bio-medicine. MotivationThis research study encourages the scientists and researchers about the heat transport features, fluid properties, and its influencing aspects, influencing mechanisms of nanofluids and influencing rules. The current article elaborates the latest study effects in the open workings on nanofluids, with the intention of scientists in the field of energy variation which have an extra broad and perfect sympathetic understanding of the energy modification possessions and usages of nanofluids. Purpose of the workThis paper sums up the modern and new features of 3D magneto radiative Carreau fluid considering the thermal phenomenon of Joule heating, heat sink/source, convective concept and solutal phenomenon of activation energy and chemical reaction. Additionally, with nonlinear mixed convection, Soret-Dufour influence and zero mass flux theory are studied. MethodologyThe considered problem of Carreau nanofluid with diverse aspects has been solved numerically via the bvp4c algorithm. ResultsThe larger values of thermo Biot and Dufour factors enhance the Carreau fluid temperature field. The Brownian factor has a reverse influence on temperature and concentration graphs. The Soret number impact on concentration field and Eckert number on temperature field have the same performance. Moreover, thermophoretic and Soret numbers exaggerate the transport rate of heat. It is also noted that average increase of Nusselt number with respect toNT is 3.69% while average decrease of Nusselt number with respect of Ec is 7.75%.
