Abstract

This study exhibited the investigation of magnetohydrodynamics (MHD) boundary layer phenomenon of Casson and Williamson nanofluids, which was flowing on an inclined cylindrical surface. The impact of linear order chemical reaction with thermal radiation had been considered in multiphase flows. By taking the assistance of compact visual FORTRAN 6.6a programming algorithm, the finite scheme was imposed explicitly for attaining the dimensionless form of the fundamental equations. The convergence criterion had also been established for the exactness of the pertinent parameters. It was observed that the ongoing work converged for Lewis number Le ≥ 0.036 and Prandtl number Pr ≥ 0.52 . A tabular comparison had been presented to validate the numerical modelling, and a favourable result was attained. The obtained outcomes were analysed for diversified pertinent parameters on different flow fields. Besides, the influence of Casson and Williamson parameters were also displayed through streamlines and isotherms. However, this study investigated the fluid behavior of Lorentz force effects together with Nano-particle which increase the thermal conductivity of both fluids. The study has been done in two different phase of fluid flows. Finally, it was concluded that the mass and heat transform accomplishment of Williamson fluid was relatively lower compared to Casson fluid. The comparison was also done significantly through the updated visualisation of fluid flow in this study.
