This study aims to analyze the electromagnetic, hydro-thermal characteristics of hybrid nanofluid (Fe3O4-CoFe2O4/EG-water) flow over a permeable plate considering Thompson and Troian slip, suction/injection effects. By employing suitable similarity transformations, governing partial differential equations (PDEs) describing are converted into set highly nonlinear ordinary (ODEs). These transformed computationally solved using "bvp4c technique" in MATLAB. The detailed graphs illustrate impact various factors for instance, Hartmann number, electric parameter, velocity slip critical shear rate, permeability heat generation/absorption parameter suction/blowing on temperature distributions. Also, tabular data facilitates quantitative examination these influences. profiles exhibit opposite nature influenced by such as Furthermore, parameters increase, so do absolute values Nusselt number. Conversely, higher Eckert number cause decrease values.

Hybrid nanofluids show great potential for heat transport applications such as solar thermal systems, car cooling sinks, and energy storage. They possess better stability properties compared to standard nanofluids. In this study, a base fluid, methanol, is injected into an electrically conducting heat-generating/absorbing disk of permeable boundary, dual solutions are obtained. Two alternative models, Xue Hamilton-Crosser considered, their conductivities contrasted. Furthermore, radiation ohmic heating also convective boundary conditions utilized simulate overall gains or losses resulting from conduction, forced natural convection between nearby objects nearly constant temperature. Using similarity transform, the governing equations obtained numerically solved via bvp4c, finite difference method. It observed that presence magnetic field shrinking elevate rate wall stress. Additionally, skin friction coefficient distribution increase with transmission constraint while fluid flow diminish. particle clustering nano-layer creation suggest model exhibits conductivity than model.
