Impact of Cattaneo-Christov Heat Flux on Mixed Convection Flow of a Ternary Hybrid(Cu-Al2O3-TiO2/H2O)Nanofluid Over an Elongated Sheet: A Comparative Analysis

The transfer of heat is an ineluctable part of science and engineering. The ternary hybrid nanofluid with its refined thermal properties exhibits superior heat transport capacity compared to hybrid nanofluids. Bearing in mind the extensive applications of this advanced fluid,the current research article deliberately investigates the impact of Cattaneo-Christov heat flux on the flow of a ternary hybrid nanofluid over an elongated sheet in the existence of thermal radiation. The proposed model is formulated by considering a base fluid of water dispersed with three distinct nanoparticles,Cu, Al₂O₃ and TiO₂. An application of the similarity transformation is made to change the controlling equations of the flow in dimensionless form. A numerical solution of the resulting equations is obtained by utilizing the bvp4c algorithm in MATLAB software. The results revealed that amplification in the values of the mixed convection parameter enhances the velocity profile of the ternary hybrid nanofluid and there is an advanced thermal transmission rate under the sway of Cattaneo-Christov thermal theory. It is further inferred from the current study that with varying volume fractions, trihybrid nanofluid demonstrates approximately 1.82-5.46% greater heat transfer than TiO₂/H₂O nanofluid and exhibits a stupendous thermal transmission rate over hybrid nanofluid and nanofluid.
