Electrically conducting mixed convective flow of a hybrid nanoliquid over a rotating sphere with nonlinear thermal radiation

Abstract

Hybrid nanofluids have specific features that make them suitable for various industrial and engineering applications. The engineering and industrial applications of hybrid nanofluids are refrigeration, air conditioning, drug delivery, cancer therapy, electronic cooling, gearboxes, power plants, engines, bearings, air pollution control, solar thermal collectors, and water treatment. The existing model is presented for the theoretical examination of the hybrid nanofluid flow at the stagnant point of a gyrating sphere. With applications of the quadratic Rosseland thermal radiation, the variations in quadratic density temperature is scrutinized. In this analysis, two different nanoparticles such as silver Ag and manganese zinc ferrite MnZnFe2O4 nanoparticles have mixed with kerosene oil. The main equations of the existing problem are framed by using the concepts of boundary layer theory. On the basis of this theory, the nonlinear PDEs are used in the formulation of the existing problem. HAM technique is used for evaluation of current flow problem. Some significant findings of the current model are that the heat transmission intensifies for upsurge in radiation factor and nanoparticles volume fractions. Also, it is found that the velocity distribution decreases for rise in the positive constant. Further, it has discovered that thermal distribution is higher for growth in radiation factor and temperature ratio factor.
