Non-Fourier modeling and numerical simulations on heat and transfer in tangent hyperbolic nanofluid subjected to chemical reactions

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. Shearthinning 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.

Automated summary

This study focuses on modeling two-phase chemical reactions in tangent hyperbolic fluid with nanoparticles and investigating the effects of various parameters using mathematical laws and models. The research findings reveal shear-thinning and shear-thickening behaviors, as well as the impact of particle resistance on heat dissipation and the difference in heat dissipation between hybrid and mono nanofluids. The Lorentz force induced by fluid motion with hybrid nanoparticles is greater than that induced by pure nanofluid. The thermal relaxation characteristics affect the equilibrium of the fluid and its temperature field.
