Computational analysis on radiative non-Newtonian Carreau nanofluid flow in a microchannel under the magnetic properties

Abstract

Micro uidic technology and Micro Electromechanical Systems (MEMSs) have received much attention in science and engineering elds over the last few years. MEMSs are found in many areas like heat exchangers, chemical separation devices, biochemical analysis, and micro pumps. Keeping these facts in mind, the prime purpose of the current paper is to present the ow of Carreau nano uids through a microchannel with electro-osmosis, Joule heating, and chemical reactions. The e ect of the external magnetic eld is considered into account. For the problem formulation, the Cartesian coordinate system is considered. The perturbed solutions are presented by making use of regular perturbation method. The graphical results are prepared based on di erent values of uid ow phenomena like velocity, temperature, solutal nano-particle concentration, Sherwood number, and Nusselt number with di erent uid variables. According to our analysis, velocity decrement is identi ed with respect to enhancing the magnetic parameter (Hartmann number). The Schmidt number, Radiation term, Prandtl number, and chemical reaction term increased the solutal nano-particle concentration. The outcomes of the Newtonian liquid model can be obtained from our scrutiny. The present scrutiny has many applications in engineering sciences such as electromagnetic micro pumps and nanomechanics.

Numerical Analysis of the Magnetic Dipole Effect on a Radiative Ferromagnetic Liquid Flowing over a Porous Stretched Sheet

“…The term "nanofluid" was used to describe a fluid containing particles on the nanoscale. With their longterm stability, minimal clogging, and thermal conductivity, nano-liquids have the potential to be useful in power engines, nuclear reactors, microelectronics, pharmaceuticals, solar energy, and so on [5][6][7][8][9][10][11]. Furthermore, there are no side consequences to dealing with nanoparticles, such as a drop in pressure, erosion, or sedimentation.…”
