Abstract
This study explores the combined impacts of heat source and radiation on the boundary layer of magnetohydrodynamic stagnation point flow of a copper–water nanofluid over an exponentially stretching slippery surface. The fundamental governing partial differential equations of mass, momentum, and energy in the model are transformed into dimensionless ordinary differential equations through similarity transformations. These derived ordinary differential equations are then converted into an initial value problem and solved numerically using the Runge-Kutta-Fehlberg technique. The results are analyzed for parameters relevant to engineering and industrial applications, encompassing velocity, temperature, skin friction, and Nusselt number. The analysis reveals that an increase in the values of heat source and radiation parameters leads to higher temperature and Nusselt number in the copper–water nanofluid flow. Conversely, an increase in the magnetic parameter results in a decrease in the temperature profile. These findings are compared with other reported results for a special case and are subsequently presented graphically and discussed in the context of engineering and industrial applications.
