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.
Heat transfer is of vital importance because of its application in industries. A new nanofluid class called hybrid nanofluid is being used to boost ordinary fluids' heat transfer capabilities and has a higher heat exponent than nanofluids. The hybrid nanofluids (HNFs) are associated with two-element nanoparticles immersed in a base fluid. The steady hybrid nanofluid flowing and thermal transport characteristics passed overhead a slippery surface are investigated in this research. The impact of nanosolid particle shapes, Porosity material, heat source, viscous dissipative flow, and radiative flux are also involved in this examination. In a regime of partial-differential equations (PDEs), the predominant flow equations are formulated. Keller-box's computational technique is the utilized method to detect the self-similar solution for formulas transformed into ordinary-differential equations (ODEs) through appropriate transmutations. Williamson hybrid nanofluid has been considered for this work, which consists of double diverse kinds of nanoparticle, Copper (Cu) and Silicon dioxide (SiO2) in the rich viscous based fluid of kind EO (Engine Oil). The noteworthy result of this analysis is that the comparing thermal transmission level of such kind of fluid (SiO2-Cu/EO) which has progressively more upsurges as compared to traditional nanofluids (Cu-EO). The lamina-shaped elements cause the utmost important thermal conductivity in the boundary-layer, whilst the lowermost thermal conductivity is detected in sphere shaped nanoparticles.
