Entropy Amplified solitary phase relative probe on engine oil based hybrid nanofluid

Wasim Jamshed et al.

Summary: Heat transfer is crucial in industries and a new nanofluid called hybrid nanofluid is being used to enhance heat transfer capabilities. This research investigates the characteristics of steady hybrid nanofluid flow and thermal transport over a slippery surface, taking into account various factors such as nanosolid particle shapes, material porosity, heat source, viscous dissipative flow, and radiative flux. The noteworthy finding is that the thermal transmission level of the hybrid nanofluid (SiO2-Cu/EO) is higher compared to traditional nanofluids (Cu-EO), with lamina-shaped elements demonstrating higher thermal conductivity in the boundary-layer.

Summary: This article investigates the flow of an incompressible micropolar Prandtl fluid over a porous stretching sheet, incorporating effects such as exponential temperature-dependent heat source, higher-order chemical reaction viscous dissipation, nonlinear thermal radiation, and multiple convective surface boundary conditions.
