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.
Highlights
The diverse nature of fluids in industry and nature has led researchers to propose new and novel constitutive relations for examining the rheological characteristics of fluid and the impact of rheology of such fluids on the transportation of energy and mass in them
The governing complex models associated with mono and hybrid nanofluids suspended with dust particles are solved in order to investigate the role of monotonicity and hybridity of nano-sized particles in dust suspended micropolar fluid
Boundary layer thickness (BLT) associated with mono dusty nanofluid and hybrid dusty nanofluid is seen to reduce with variation in vortex viscosity
Summary
The diverse nature of fluids in industry and nature has led researchers to propose new and novel constitutive relations for examining the rheological characteristics of fluid and the impact of rheology of such fluids on the transportation of energy and mass in them. The research on simultaneous mechanisms in non-Newtonian fluid is extensively applied in the development of various engineering processes. Transportation of fluid and various species in fluid flows has been studied extensively.. The characteristics of transportation of heat energy and species are significantly influenced by the rheology of the non-Newtonian structure of fluid by which energy and species are being transported. Micropolar fluid is a classical non-Newtonian rheology, and transportation of momentum and energy can be modeled by a set of momentum and energy equations and Fick’s second laws. In contrast to other fluids, an additional transportation equation is needed to model various aspects of the flow characteristics. Various studies on this topic have been published.
