Abstract
The proposed study presents a comprehensive investigation of the combined effects of viscous dissipation and Joule heating on chemically reactive magnetohydrodynamic (MHD) micropolar fluid flow over a nonlinear stretching sheet, incorporating the influences of radiative heat transfer, heat source, and convective boundary conditions. The current study investigates the flow of a type of fluid called micropolar fluid in a stretched 2D space. This fluid is viscous, and the flow is influenced by convective boundary conditions. Mathematical equations are derived considering factors such as heat, friction, electrical effects, chemical reactions, and radiation heat transfer. The fluid can conduct electricity when exposed to an external magnetic field. The complex partial differential equations governing the boundary layer flow are simplified into ordinary differential equations using a technique known as similarity transformation. The problem is solved using the Runge-Kutta-Fehlberg method with a shooting technique. Graphs are generated to analyze how physical factors influence temperature and concentration profiles. The skin friction coefficient, local Nusselt number, and local Sherwood number are calculated and studied. In this study, we compare our results with those of other research and find good agreement.
期刊介绍:
Nano-Structures & Nano-Objects is a new journal devoted to all aspects of the synthesis and the properties of this new flourishing domain. The journal is devoted to novel architectures at the nano-level with an emphasis on new synthesis and characterization methods. The journal is focused on the objects rather than on their applications. However, the research for new applications of original nano-structures & nano-objects in various fields such as nano-electronics, energy conversion, catalysis, drug delivery and nano-medicine is also welcome. The scope of Nano-Structures & Nano-Objects involves: -Metal and alloy nanoparticles with complex nanostructures such as shape control, core-shell and dumbells -Oxide nanoparticles and nanostructures, with complex oxide/metal, oxide/surface and oxide /organic interfaces -Inorganic semi-conducting nanoparticles (quantum dots) with an emphasis on new phases, structures, shapes and complexity -Nanostructures involving molecular inorganic species such as nanoparticles of coordination compounds, molecular magnets, spin transition nanoparticles etc. or organic nano-objects, in particular for molecular electronics -Nanostructured materials such as nano-MOFs and nano-zeolites -Hetero-junctions between molecules and nano-objects, between different nano-objects & nanostructures or between nano-objects & nanostructures and surfaces -Methods of characterization specific of the nano size or adapted for the nano size such as X-ray and neutron scattering, light scattering, NMR, Raman, Plasmonics, near field microscopies, various TEM and SEM techniques, magnetic studies, etc .
