Abstract
Two-phase chemical reactions (homogeneous-heterogeneous) in tangent hyperbolic fluid with nanoparticles subjected to heat transfer are modeled using mathematical laws and models. The solutions of governing models are derived by the finite element method (FEM). The solutions are checked to be grid-independent and convergent solutions are obtained which are further used for simulations of effects of various parameters. Shear-thinning and shear-thickening behaviors are predicted from the FEM solutions for the various values of the power-law index and other parameters. The tangent hyperbolic rheological behavior is determined through variation of Wessienberg number. The diverse behavior of fluid motion for the values of the Wessienberg number is observed. Electric current experiences resistance by the particles of the fluid. Hence, more heat is dissipated by the Ohmic mechanism. It is also noted that hybrid nanofluid dissipates more heat than that by mono nanofluid. The Lorentz force induced by the motion of pure and nanofluid is less than that induced by the motion of fluid with hybrid nanoparticles. Thermal relaxation characteristics reinforces the fluid in maintaining its thermal equilibrium and therefore temperature field for both types of fluids has to show a decreasing behavior for an increase in thermal relaxation parameter. The increasing behavior of homogeneous chemical reaction strength on concentration profile is noted whilest the oppositein concentration profile trend is observed for heterogeneous chemical reaction strength.
