Mathematical modeling of stagnation region nanofluid flow through Darcy–Forchheimer space taking into account inconsistent heat source/sink

The primary target of present research is to examine the application of OHAM (optimal homotopy asymptotic method) for a nanofluid transport through Darcy Forchheimer space toward the stagnation region by comparing stretching and straining forces. The porous matrix is suspended with nanofluid, and the flow field is under inconsistent heat source/sink influence. The solutions of guiding boundary layer equations report that pattern of primary velocity profiles are inverted by stagnation region flow strength. Straightforward relation of Forchheimer number with heat transfer has also been observed when stagnation forces dominate stretching forces. The novelty of present article lies in vector form presentation to OHAM and in the comparative analysis of stretching and straining forces.
