The Role of External Heat Sources and Chemical Reactions for Enhanced Heat Transfer through Maxwell Nanofluid Flow

Abstract

This research addresses finding the dynamics of heat transfer in two-dimensional MHD Maxwell nanoflu-ids flow under the influence of mixed convection and activation energy. The heat source is strategically positioned to take advantage of convective heat transfer and increase the overall thermal performance. Numerical simulations employing computational fluid dynamics (CFD) approaches are used to evaluate the improved thermal transfer efficiency. The governing equations, which comprise the continuity, momentum, energy, and species transport equations, are addressed using appropriate similarity transformations acquired from a PDE (Partial differential equations) model that has been turned into an ODE(ordinary differential equations). MATLAB is used to solve such a nonlinear ODE model. The effects of many parameters, such as nanoparticle concentration, the intensity of an external heat source, and chemical reaction speeds, are intentionally explored. The fluid flow declaration is evaluated in terms of viscosity, and porosity. It was discovered that increasing inputs of rotation, porosity factor, activation energy, and magnetic effect resulted in a significant increase in the profile of temperature. The variational patterns of Nusselt number and skin friction are numerically performed at a rectangular stretching surface.
