Numerical investigation on transport of momenta and energy in micropolar fluid suspended with dusty, mono and hybrid nano-structures

Abstract

Computational fluid dynamics (CFD) tools are applied to model transportation activity in micropolar fluid suspension with density particles and mono and hybrid metallic nano-sized structures. Highly complex computational models obtained by CFD simulations are executed via the finite element method. Galerkin residuals are approximated by Galerkin approximations. The assembled nonlinear system is linearized and solved iteratively under reasonable computational tolerance. A notable impact of vortex viscosity is observed during transportation of macro- and micro-momentum. The velocity of dust particles has been predicted via the variation of dust particle interaction parameter. Angular velocity for both mono and hybrid nanofluids is found to increase as a function of vortex viscosity. Furthermore, it is noted that the micro-rotation field associated with mono-nanofluid has a higher value than the micro-rotation field associated with hybrid nanofluids.
