Abstract
The primary and foremost objective of the recent assessment is to offer a comprehensive analysis regarding the heat transfer of fractional unsteady magnetohydrodynamic flow of viscoelastic hybrid nanofluids (blend of MWCNTs and SWCNTs) over an inclined surface fixed in a Darcy porous medium where the impact of mixed convection is also taken into account. We have also presented the Scott Blair model and fractional Fourier's law in the constitutive relations. Furthermore, we have employed Caputo fractional derivatives (CFD) (α and β) together with fractional momentum and thermal relaxation times λ1 and λ2 to model the flow problem under consideration to attain flow and heat transfer control. Since the principal FPDEs are nonlinear and hence numerical solved by utilizing FD discretization combined with the L1 method. Simulated outcomes of velocity and temperature are elaborated in both cases, i.e., the single and hybrid nanofluids. The obtained results are of significant value due to FD, CNTs. The same may be utilized to proficiently tackle thermal management challenges like the achievement of temperature control in automobile engines, boilers, grinders, heat exchangers, and refrigerators, etc.
