Abstract Novel correlations for thermophysical properties of base fluid (micropolar fluid) and hybrid nanostructures are used to analyze the impact of the inclusion of copper oxide and titanium dioxide thermal enhancement in the polymer with microstructures. The polymers are assumed to be characterized by micropolar rheological equations. The models from governing laws are derived and are simplified by boundary approximations. The boundary conditions are based on no-slip. The finite element method (FEM) is used for numerical solutions. The mesh and convergence analysis are tested. The convergent solutions are further utilized for the simulation process. The wall shear and couple stresses are examined and the heat transfer rate is visualized. This study has predicted thermal optimization due to the simultaneous inclusion of copper oxide and titanium dioxide nanoparticles. The hybrid nanofluid is an efficient working fluid than the pure fluid. However, the presence of hybrid nanoparticles in micropolar fluid makes the viscous region wider. It is found that nano polymers with C u O experience less resistive force due to porous medium as compare to hybrid nanopolymers ( C u O − T i O 2 − polymers). The angular motion slows down as the vortex viscosity parameter is increased. However, this decrease is more noticeable in hybrid nano-polymers than that in nanopolymers.
