Dissipative heat impact on the flow of Cu-water micropolar nanofluid within a parallel channel with thermal radiation

Abstract

The utility of micropolar nanofluid presents challenges nowadays in various industrial sectors as well as biomedical areas due to its higher thermal properties. Generally, these are useful in electronic cooling devices, drug delivery processes, hyperthermia treatment, etc. The current problematic model aims at the behavior of particle concentration of copper nanoparticles on the motion of micropolar fluid via two parallel plates packed within a porous matrix. The conducting fluid, with the interaction of radiative heat and dissipation energy, energies the flow and heat transport phenomena. The modeled problem equipped with aforesaid properties is transmuted to ordinary for the suitable choice of similarity rules, and then, numerical technique is adopted to handle the governing equations. The simulation of the characterizing parameters is presented through graphs followed by the comparative analysis with the existing results in particular case. The main conclusions are as follows: The thickness is greatly increased by the Reynolds number, while it is attenuated by the magnetization provided by the interplay of the applied magnetic field and the medium's permeability. As a result of amplified radiating heat, the fluid temperature moves toward the top plate region, indicating a greater fluid temperature and a greater cooling impact at the bottom region.
