Effects of second order chemical reaction on MHD forced convection Cu, Ag, and Fe3O4 nanoparticles of Jeffrey Nanofluid over a moving plate in a porous medium in the presence of heat source/sink

Abstract

The objective of the current research is to determine how a second order chemical reaction will affect the magnetohydrodynamic flow of a water-based Jeffrey nanofluid containing Copper (Cu), Silver (Ag), and Ferrous Ferric Oxide (Fe3O4) nanoparticles over a flowing stream embedded in a porous medium in the presence of a heat source/sink. The governing system of PDEs is converted into nonlinear ODEs using the similarity transformation approach, and these nonlinear ODEs are then resolved using MATLAB's built-in solver, bvp4c. In a single plot of three nanoparticles and tables, the output of the nanofluid velocity, temperature, and concentration are displayed for the included material properties as well as the related engineering physical parameters like coefficient of skin friction and rate of heat and mass transfer. This model has been rather successfully validated. The results indicate that the nanofluid 𝜃𝜃(𝜂𝜂) and �(𝜂𝜂) profiles decline as λ1 increases, while this behavior is opposite for the distributions of 𝑓𝑓′(𝜂𝜂). The kinetic energy of fluid particles decelerates because of the high viscosity. The study demonstrates the significance of three nanoparticles in the disciplines of biocompatibility engineering and medicines. Additionally, these nanoparticles are utilized in engineering, physics, space technology, operations involving high temperatures and cooling, pharmaceuticals, biosensors, paints, cosmetics, conductive coatings, and medical devices.
