Dual solution and stability analysis of chemically reactive Darcy Forchheimer MHD flow of CuO + Ag / micropolar hybrid nanofluid over the porous stretching/shrinking sheet

Abstract

The hybrid nanofluid has become an interesting field of the research due to having higher thermal conductance when compared to traditional common fluids. Due to their significance, two dimensional (2D) of CuO + Ag / water-based micropolar hybrid nanofluid flow on a stretching/shrinking sheet with Darcy Forchheimer, magnetohydrodynamics (MHD) and radiative impacts is accounted. Other physical effects like heat sink/source, micro material and chemical reactions, and porosity factor are also taken into consideration. Due to requirements of the used numerical methodology, the governing partial differential equations (PDEs) are changed to ordinary differential equations (ODEs) through similarity transformations. Later on, the ODEs are solved through shooting technique in Maple software. Due to raising duality in solutions, the stability of the solutions has been done in MATLAB through BVP4C code, where first solution is found as a feasible and stable solution and second one is unstable that rises due to high nonlinearity in equations. Some of the main findings show that an increment in volume fraction of nanoparticles and Forchheimer number leads to increase in the fluid velocity, while reverse trends are noticed within higher suction and micro material parameters. An increment in nanoparticles volume fraction, Forchheimer number, Biot number, radiation and magnetic parameters enhanced the temperature profiles.
