Analysis of Cattaneo-Christov Heat Flux in Nanofluid, Hybrid, and Ternary Hybrid Nanofluid Flow Between Rotating Stretchable Disks

The behaviour of nanofluid, hybrid, and ternary hybrid nanofluid flow between stretchy, spinning discs is examined in this work using the Cattaneo-Christov heat flux model. The driving momentum and energy equations are found in a cylindrical polar coordinate system to show how the flow moves and how heat moves. Once these equations have been non-dimensionalized using suitable similarity transformations, the system is simplified, and analysis becomes easier. The spectral quasi-linearization method, a reliable computational approach appropriate for intricate fluid systems, is used to numerically solve the resulting equations. Several graphs and tables that show how different physical parameters affect flow and thermal behaviour are used to convey the results. Interestingly, the findings show that hybrid nanofluids with aluminium alloys have better flow properties than ternary hybrid nanofluids and simple nanofluids. This improved performance demonstrates the promise of hybrid nanofluids based on aluminium as high-conductivity fluids, which makes them especially beneficial for sectors needing effective thermal control. Since aluminum-alloy hybrid nanofluids have superior conducting qualities, the study advises that businesses that are interested in improving their cooling systems should give serious consideration to implementing them.
