Casson-Williamson ternary hybrid nanofluid flow over a yawed cylinder with the impacts of multiple slips

Purpose: Many industries use non-Newtonian ternary hybrid nanofluids (THNF) because of how well they control rheological and heat transport. This being the case, this paper aims to numerically study the Casson-Williamson THNF flow over a yawed cylinder, considering the effects of several slips and an inclined magnetic field. The THNF comprises Al₂O₃-TiO₂-SiO₂ nanoparticles because they improve heat transmission due to large thermal conductivity. Design/methodology/approach: Applying suitable nonsimilarity variables transforms the coupled highly dimensional nonlinear partial differential equations (PDEs) into a system of nondimensional PDEs. To accomplish the goal of achieving the solution, an implicit finite difference approach is used in conjunction with Quasilinearization. With the assistance of a script written in MATLAB, the numerical results and the graphical representation of those solutions were ascertained. Findings: As the Casson parameter (Formula presented.) increases, there is an improvement in the velocity profiles in both chord and span orientations, while the gradients (Formula presented.) reduce for the same variations of (Formula presented.). The velocities of Casson THNF are greater than those of Casson-Williamson THNF. Approximately, a 202% and a 32% ascension are remarked in the magnitudes of (Formula presented.) and (Formula presented.) for Casson-Williamson THNF than the Casson THNF only. When velocity slip attribute (Formula presented.) jumps to 1 from 0.5, magnitude of both (Formula presented.) and (Formula presented.) fell down and it is reflected to be 396% at (Formula presented.), (Formula presented.) and (Formula presented.). An augmentation in thermal jump results in advanced fluid temperature and lower (Formula presented.). In particular, about 159% of down drift is detected when (Formula presented.) taking 1. Originality/value: There is no existing research on the effects of Casson-Williamson THNF flow over a yawed cylinder with multiple slips and an angled magnetic field, according to the literature.
