Heat transfer performance of temperature-dependent Xue and Yamada-Ota hybrid nanofluid flow models past a curved stretching sheet with generalized Fourier law

In this exploration, temperature-dependent Yamada-Ota and Xue hybrid nanoliquid models are investigated over a curved stretchable surface embedded in an absorbent media. Hybrid nanofluids are formed by the combination of single and multi-walled carbon nanotubes (CNTs) as nanoparticles with engine oil as base fluid. The goal of this study is to interpret how the modified Fourier law combined with temperature-dependent thermal conductivity, Newtonian heating and variable heat source/sink enhances thermal performance. A mathematical formulation of the problem is illustrated in the curvilinear coordinates. Highly nonlinear dimensionless ODEs are solved numerically by engaging the bvp4c approach. The impression of the key parameters is illustrated graphically. Drag force coefficient and Nusselt number are highlighted through tables. It is comprehended that the fluid velocity decays on augmenting the velocity slip parameter while elevates on amplifying the curvature parameter. Furthermore, an enhancement in the temperature field is noted for the conjugate parameter. A significant correlation with the existing outcomes is perceived when a comparison with the existing literature is made.

Automated summary

In this study, temperature-dependent Yamada-Ota and Xue hybrid nanoliquid models were used to investigate the thermal performance over a curved stretchable surface embedded in an absorbent media. The results showed that the modified Fourier law combined with temperature-dependent thermal conductivity, Newtonian heating, and variable heat source/sink can enhance the thermal performance. Additionally, it was observed that the fluid velocity decreases with an increase in the velocity slip parameter and increases with an increase in the curvature parameter. Moreover, the temperature field is enhanced with the conjugate parameter. The results are in good agreement with the existing literature.
