Impact of monocity and hybridity of nano-structures on thermal performance of micropolar fluid with novel heat flux theory: the Cattaneo-Christov heat flux theory

Thermal relaxation phenomenon and generalized heat flux theory accurately determine the heat transfer for characteristics in industrial fluid like polymers. The rheology of polymers is best characterized by vortex and spin gradient viscosities and couple stresses. This article models the impact of hybridity of nano-structures on thermal performance of the micropolar fluid using novel heat flux theory. Mathematical models are used is analyze the behavior of temperature wall heat flux. Noslip hydrodynamic boundary conditions are implemented in order to examine the thermal performance of micropolar fluid. Numerical simulations are carried out via finite element method (FEM). A remarkable impact of hybridity of nano-structures on transport of heat is noted. Dissipation of heat has played a vital role in enhancing the thermal boundary layer thickness. The heat dissipated in hybrid nanofluid is greater than heat dissipation of heat in mono-nanofluid. Temperature of both mono and hybrid nanofluid has shown a decreasing trend when Deborah number is increased. This is due to the fact that fluid restores its original thermal state and resists against thermal change in its state. Heat flux has shown increasing trend versus change in magnetic field intensity. Further, heat flux has shown increasing trend versus an increase in vortex viscosity parameter. (C) 2020 The Authors. Published by Elsevier B.V.
