Evaluating the viscous dissipation effect on dusty boger hybrid nanofluid with applications of cattaneo-christov approach: Xue and Yamada–Ota models
Аннотация
This study aims to investigate the effects of viscous dissipation on the flow of a dusty Boger hybrid nanofluid over a plate using variable thermal conductivity and the Cattaneo-Christov heat flux model. The goal of this work is to use sodium alginate fluids to determine the hybrid nanofluid's thermal mobility. For the thermal behaviour, Cu and A l 2 O 3 are used as the nanoparticles. It is particularly useful in industrial processes including polymeric and non-Newtonian fluids, such as in extrusion, chemical processing, cooling of electronic equipment, and thermal management in energy systems. The inclusion of hybrid nanoparticles enhances thermal performance, while the consideration of thermal relaxation effects via the Cattaneo–Christov model makes the analysis more realistic for high-temperature and microscale applications. Moreover, the presence of dust particles adds relevance to areas like aerospace engineering, combustion systems, and particulate-laden flows in environmental and biomedical fields. An appropriate transformation strategy is applied to transform PDEs into ODEs. The shooting method is used to establish the numerical solution. The results demonstrate that the Boger hybrid nanofluid displays an improved flow field and a lowering liquid phase thermal field for higher values of the solvent fraction factor.
