Computational analysis of chemically reactive MHD Ellis hybrid nanofluid flow through a porous medium with thermal radiation and activation energy over a stretching cylinder

The present work inspects computational analysis of magnetized 2D incompressible flow of hybrid nanofluid (𝐴𝐴7072- 𝐴𝐴7075/H2O) with Darcy-Forchheimer, nonlinear thermal radiation, chemical reaction, and activation energy impacts over a stretching cylinder. The flow problem is presented by nonlinear PDEs of continuity, momentum, energy, and concentration, which are numerically resolved by the implementation of BVP4C procedures by MATLAB software. The simultaneous study of nonlinear thermal radiation with magnetic field, chemical reaction, and activation energy effects, and 2-Dimensional nonlinear partial differential equations are modernizations of the present study that provides key insights into intensifying the thermal and mass transport potency. The inferences of dimensionless parameters, especially Schmidt number $$\\:(0.1\\:\\le\\:\\:Sc\\:\\le\\:\\:0.7),$$ chemical reaction $$\\:(0.1\\:\\le\\:\\:Rc\\:\\le\\:\\:0.4)$$ , and activation energy $$\\:(1\\le\\:\\:E\\:\\le\\:\\:2.5$$ ) regarding the concentration distributions, with thermal performance, are systematically studied graphically. Furthermore, local shear stress (Cfx), heat and masstransfer rates (Nux, Shx) are also elucidated in tabular forms. This model has been carefully verified against current data and demonstrated exceptional accuracy. Quantitatively, the local Sherwood number is improved by around 9.8% when the Schmidt number is increased from $$\\:Sc=0.1\\:to\\:0.4,$$ while the local Nusselt number is improved by roughly 29.1% when the radiation parameter is increased from $$\\:Rd=0.1\\:to\\:0.4.$$ Additionally, the skin-friction coefficient increases by about 9.3% when the magnetic parameter is increased from $$\\:M=0.1\\:to\\:0.4$$ .
