Abstract

This study investigates the heat transfer and flow dynamics of a ternary hybrid nanofluid comprising alumina, copper, and silica/titania nanoparticles dispersed in water. The analysis considers the effects of suction, magnetic field, and Joule heating over a permeable shrinking disk. A mathematical model is developed and converted to a system of differential equations using similarity transformation which then, solved numerically using the bvp4c solver in Matlab software. The study introduces a novel comparative analysis of alumina-copper-silica and alumina-copper- titania nanofluids, revealing distinct thermal conductivity behaviors and identifying critical suction values necessary for flow stabilization. Dual solutions are found within a specific range of parameters such that the minimum required suction values for flow stability, with S c = 1.2457 for alumina-copper-silica/water and S c = 1.2351 for alumina-copper- titania/water. The results indicate that increasing suction by 1% enhances the skin friction coefficient by up to 4.17% and improves heat transfer efficiency by approximately 1%, highlighting its crucial role in stabilizing the opposing flow induced by the shrinking disk. Additionally, the inclusion of 1% silica nanoparticles reduces both skin friction and heat transfer rate by approximately 0.28% and 0.85%, respectively, while 1% titania concentration increases skin friction by 3.02% but results in a slight heat transfer loss of up to 0.61%. These findings confirm the superior thermal performance of alumina-copper-titania/water, making it a promising candidate for enhanced cooling systems, energy-efficient heat exchangers, and industrial thermal management applications.
