Thermal performance of aqueous alumina–titania hybrid nanomaterials dispersed in rotating channel

Abstract

The extension of nanoliquid obtained by adding nano-powder composite or various nanoparticles in regular liquid is term as hybrid nanofluid. Hybrid nanofluids are more potential materials that significantly uplift the thermophysical feature and capacity of heat transportation instead of single nanoparticle nanoliquid. Hence, the paramount interest of this paper is to model theoretically the flow of aqueous alumina–titania hybrid nanoliquid across a rotating channel. Temperature-based viscosity is addressed. This analysis further contributes the impact of heat source and dissipation phenomena. Additionally, two different shapes of nanoparticles, namely, bricks- and needle-shaped are included. Similarity variables dimensionless the governing problem. The obtained system is solved by employing Mathematica-based NDSolve approach. The impact of various embedded variables is elucidated graphically. The presence of hybrid nanocomposite greatly affects the temperature and Nusselt number than nanoparticles. Further outcomes declared that rotation and heat source variables significantly increase the thermal field for hybrid nanophase when compared with nanophase.
