Abstract
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
β increases, there is an improvement in the velocity profiles in both chord and span orientations, while the gradients
Re1/2Cf, Re1/2C¯f reduce for the same variations of
β. 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
Re1/2Cf and
Re1/2C¯f for Casson-Williamson THNF than the Casson THNF only. When velocity slip attribute
S1 jumps to 1 from 0.5, magnitude of both
F(ξ,η) and
Re1/2Cf fell down and it is reflected to be 396% at
ξ=1,
Wi=1 and
β=1. An augmentation in thermal jump results in advanced fluid temperature and lower
Re−1/2Nu. In particular, about 159% of down drift is detected when
S2 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.
