Numerical Analysis of Cu-water Nanofluid flow in a Darcy-Forchheimer Porous Medium under the Combined Effects of Magnetic Field, Suction/Blowing, Stretchable Surface and Radiation

The article looks at what happens when you mix the effects of a magnetic field, suction/blowing, a flexible surface, and radiation on the flow of a Cu-water nanofluid in a Darcy-Forchheimer porous medium (DFPM). A Cartesian coordinate system and a rough border layer are used to show the governing equations. A similarity analysis is used to turn the system of partial differential equations (DEs) into a higher-order system of coupled-ordinary DEs. The Keller box method is then used to solve this system. A graph shows how the effects of several things work together. The main findings show that increasing the Forchheimer, magnetic, porous, and suction/injection factors slows things down. Also, the Forchheimer, magnetic, and porous properties slow down the rate of heat transfer, while force or injection does the opposite.
