| Summary: | This investigation focuses on the application of the computational
fluid dynamics tool FLUENT to the study of flows over the NACA
63–415 airfoil at various angles of attack. With the aim of selecting the
most suitable turbulence model to simulate flow around ice-accreted
airfoils, this work concentrates on assessing the prediction capabilities
of various turbulence models on clean airfoils at the large angles
of attack that cause highly separated flows to occur. The study was
undertaken by conducting simulations with the one-equation Spalart-Allmaras (SA) model, the two-equation RNG k-ϵ and SST k-ω models, and the Reynolds stress model (RSM). Domain discretization
was carried out using general quadrilateral grids generated with
GAMBIT, the FLUENT preprocessing tool. Comparisons were made
with available experimental data. |
