Lorentz force and Brownian motion features on entropy optimization in nanofluid swirling flow through porous configuration

Nanofluid holds features to improve the thermal efficiency of various technological fluids. These materials have a broad range of industrial and engineering utilizations including energy production, cooling of engines, thermal exchanges, thermal structures, extrusion procedures hybrid power plants, etc. Application in the stated sectors proposed and motivated us to use nanofluids with improved characteristics, especially thermal features. Here magnetized nanofluid flow via swirling and stretchable cylinder embedded in porous space is investigated. Entropy minimization in nanofluid with Lorentz force is explored. Energy expression is subjected to Joule heating, and energy dissipation, and radiation are included for more needed and realistic applications. Endothermic/exothermic reaction with activation energy is further considered. The governing PDEs are transformed employing transformations and then treated using a numerical method. The consequences of various parameters on different aspects are displayed via tables and graphical visualization. Outcomes declares that temperature of nanofluid is higher for exothermic parameter. Furthermore, entropy enhances with increase in magnetic variable.
