摘要

, Hybrid nanoparticles correlations together with governing models for the flow of micropolar fluid are used to develop novel complex coupled nonlinear set of differential equations. The solutions are computed by using the finite element method (FEM) and results are validated after convergence and grid-free analysis. The macroscopic velocity and micro-rotation field are investigated versus parametric variation. The temperature field is examined for various emerging dimensionless parameters. A significant improvement in the thermal performance of micropolar fluid due to simultaneous dispersion of Cu and Al2O3 (hybrid nanoparticles) is noted. Therefore, simultaneous dispersion of Cu and Al2O3 for significant improvement in thermal performance of micropolar fluid is recommended rather the dispersion of copper nanoparticles. Surprisingly micro rotation field for nano micropolar mixture near the vicinity of the wall is less than the micro-rotation field for hybrid nano-micropolar fluid. However, away from the wall opposite dynamics for the micro-rotation field are observed.
