Energy transport phenomenon via Joule heating and aspects of Arrhenius activation energy in Maxwell nanofluid

Abstract

Recent progresses in the customization of nanofluids to acquire particular thermophysical aspects have controlled a growth in the basis for an enhanced sympathetic of the numerous factors that influence thermal conductivity. The term nanofluid rises to the mixture of any nano-scale material with a base liquid. While studies of the progress and use of nanofluids have extended intensely in the former span, the amount of commercialized uses of nanofluids is a bit restricted, with the bulk of the study absorbed on studies of the concept and essential science. Therefore the thermal phenomena of non-uniform heat sink/source, Joule heating, and variable conductivity with the properties of mixed convection in magnetite Maxwell nanofluid have been elaborated. Additionally, the concept of activation energy with chemical reaction is also examined. To incorporate the significance of thermophoretic and Brownian dispersal, Buongiorno nanofluid thought is ratified. The achieved ODEs have been elucidated via homotopic algorithm. The enactments of functioning factors are studied. The heat sink factor and Eckert number enhance the temperature field; however, thermophoretic and Brownian factors have conflicting performance on the concentration field. Furthermore, the heat transport rate declines for thermophoretic and Brownian factors.
