Impact of Activation Energy on Maxwell Nanofluid in a Porous Medium

The ferromagnetic flow of Maxwell nanoliquid past a stretching surface is the focus of this endeavor. The flow is modeled in a porous medium obeying Darcy’s law and is also subjected to the effects of magnetic dipole, nonlinear radiative heat flux, and activation energy. Using proper transformation, the governing system of partial differential equations (PDEs) transforms into ordinary differential equations (ODEs). The solution process employs a shooting approach. For nanofluid concentration, temperature, velocity, skin fraction, Sherwood number, and Nusselt number, the effects of relevant non-dimensional flow parameters and numbers are explored. The results show that the porosity, elastic, and ferromagnetic parameters all reduce nanofluid velocity. The nanofluid temperature drops as the ferromagnetic and Prandtl numbers increase, while the nanofluid temperature rises to enhance the temperature ratio and radiative heat parameters. The nanofluid concentration profile rises due to the non-dimensional activation energy and falls as the Schmidt number increases.
