Exploring the Influence of Porosity, Stretchable Surface, and Suction/Blowing on Darcy-Forchheimer Cu-Water Nanofluid Flow

This article discusses the combined impacts of suction/blowing and magneto-hydrodynamic on the heat exchange and flow of Cu-water naofluid via a stretchable surface in Darcy-Forchheimer porous medium is considered in the occurrence of radiation effects. In the process of mathematically modelling governing equations, the boundary layer approximation is used as a tool. The system of PDE’s is converted into higher non-linear system of coupled ODE’s by utilizing similarity analysis, which is tackled by employing Keller box method. The physiological importance of the characteristics that are relevant to different aspects are analyzed through charts and graph. The key results include that velocity diminishes for rising values of Forchhiemer, magnetic, porous and suction/injection parameters. The Eckert number, Forchhiemer, magnetic and porous parameters play role in tumbling the rate of heat transfer while reverse behaviour was observed in presence of suction/injection.
