Abstract
To enhance heat and mass transfer, the use of hybrid nano-particles in shear rate dependent viscous fluid is of great significance in view of applications. Here in the considered problem, MXene base material titanium carbide and aluminum oxide (TiC - Al2O3) hybrid nano-particles are dispersed in the C2H6O2 (Ethylene glycol) as a base fluid. The obtained hybrid nanofluid is used to analyze the thermal performance of incompressible Carreau-Yasuda boundary layer flow. The finite element method (FEM) is implemented to find the numerical solution of the boundary value problems. The effects of magnetic field, chemical reaction parameters on velocity, thermal enhancement and mass transport are explored. It is worth noticing that the thermal efficiency of the designed system is greater in the Carreau-Yasuda hybrid nanofluid than the Carreau-Yasuda nanofluid. The velocity profile in x and y - direction enhanced as the value of the Weissenberg number increased. Interestingly, the intensity of the magnetic field increased the wall shear stresses and heat transfer rate of the Carreau-Yasuda hybrid nanofluid and the Carreau-Yasuda nanofluid. For the destructive chemical reaction, mass transfer rate increases and for the case of generative chemical processes, however, the opposite tendency is observed. In contrast to the dispersion of a single type of nano-particles (i.e.Al2O3), simultaneous dispersion of hybrid nano-particles (TiC Al2O3) in Carreau-Yasuda fluid resulted an increase in thermal efficiency of working fluid. This work gives a new pathway/paradigm to develop a new kind of efficient hybrid nanofluid to minimize energy loss.
