Abstract
A significant and developing area of fluid dynamics is flow control. Due to its frequent occurrence in engineering and industrial applications, it means a tiny modification of a configuration providing an ideally big engineering benefit, such as drag reduction, lift enhancement, mixing enhancement, or noise reduction. MHD Active and Passive Controls Mixed convection nanofluid flow, including buoyant forces and viscous dissipation in the presence of chemical reaction, over a vertical plate. Using self-similarity variables, the system of highly nonlinear partial differential equations is first converted to a system of ordinary differential equations. The Richardson extrapolation enhancer and the midrich algorithm are then used to solve the resulting boundary problem system. We applied realistic Prandtl numbers of 0.71, which correspond to air at a temperature of 25 °C and a single atmospheric pressure. 2.62 was chosen as the Schmidt number to reflect the diffusing chemical species of propyl benzene. When the contributions of buoyant forces, viscous dissipation, and the presence of chemical reaction are taken to be zero, existing results are compared with our numerical result to validate it. Graphs and tables were used to show the impact of different controlling parameters, and a thorough discussion followed.
