Non-Fourier Thermal Enhancement in Non-Newtonian Materials with Nano and Hybrid Nano-structures in Porous Medium

Williamson stress-strain correlations are shear rate dependent correlations and describe the rheology of various polymers. Such, polymers exhibit non-Fourier diffusion of heat and mass. Therefore, classical transport models are insufficient to characterize the transport of heat and mass in such polymers. Hence, generalized non-Fourier models are utilized here in this investigation. The impact of suspension of hybrid nano-structures on the enhancement in thermal efficiency of Williamson fluid is aimed to investigate. Thermal relaxation phenomenon has shown significant impact on heat and mass transport in fluids flowing in porous medium. Therefore, usage of classical laws and Fourier heat conduction leads to erroneous outcomes. Therefore, non-Fourier heat conduction and non-classical Ficks law will be used to model simultaneous transport of heat and mass in fluids obeying non-Newtonian rgheological relationship between shear stress and rate strain. Three different non-Newtonian fluids models will be chosen for modelling of transport phenomena using nonclassical laws (non-Fourier law of heat conduction). For numerical simulations, finite element method will be used. The simulations under parametric variations will be displayed and outcomes will be noted. Enhancement in thermal performance of working fluids via suspension of nano and hybrid nanoparticles will be examined and future recommendation for thermal system will be made. Outcomes will be validated with comparison of already published/available benchmarks.
