Abstract

There are many applications for thermo-solutal Marangoni convection in science and engineering. Projectiles, thermal transportation, electrical fuel, gas turbines, nuclear power plants, renewable energy, and aeronautical engineering are just a few examples of the applications of these two ideas. Considering the aforementioned uses, the present work examines the characteristics of thermo-solutal Marangon convection on the Darcy-Forchheimer stagnation point flow of MHD tetra hybrid nanofluid around a sphere rotating with activation energy. A tetra hybrid nanofluid composed of copper (Cu), molybdenum disulfide (MOS₂), titanium oxide (TiO_2,), iron oxide (Fe₃O₄), and water is used as the inappropriate fluid. Utilizing this model helps optimize energy systems such as solar collectors, increase the efficiency of chemical reactors, and improve heat and mass transfer in microelectronic cooling systems. Better performance and energy efficiency are ensured by its assistance in comprehending fluid behaviour in automotive and aerospace cooling mechanisms. Using the proper similarity variables, ordinary differential equations (ODEs) are generated from the nonlinear governing equations. A shooting method and the bvp4c method are utilized to obtain the numerical solution of the reduced boundary conditions and equations. Thermal distribution and rate of heat transfer improve but concentration distribution declines as nanoparticle volume friction rises.
