Mixed convective flow of Ag–H₂O magnetic nanofluid over a curved surface with volumetric heat generation and temperature‐dependent viscosity

Abstract The magnetic nanofluid flow over a curved surface in the presence of heat and mass mixed convection, volumetric heat generation, and higher‐order chemical reaction is studied in this study. The Maxwell Garnetts model of thermal conductivity and the Brinkman model of viscosity are used for working fluid. The numerical method is applied to assess the governing nonlinear equations of the developed model. The influence of parameters, such as buoyancy, chemical reaction, magnetic field, curvature, heat generation, and chemical reaction order are considered in the existing study. The surface diagram for Nusselt number, skin friction coefficient, and Sherwood number are revealed. From the outcomes, it can be noted that with an increase in buoyancy parameters and , the heat and mass transfer (HMT) functions declined. Moreover, the behavior of HMT is reversed when there is an escalation in the values of chemical reaction parameter . A comparison of this study with a previous study is conducted.
