Assessment of two-equation turbulence modelling for high Reynolds number hydrofoil flows. (English) Zbl 1079.76560

Summary: This paper presents an evaluation of the capability of turbulence models available in the commercial CFD code FLUENT 6.0 for their application to hydrofoil turbulent boundary layer separation flow at high Reynolds numbers. Four widely applied two-equation RANS turbulence models were assessed through comparison with experimental data at Reynolds numbers of \(8.284\times 10^6\) and \(1.657\times 10^7\). They were the standard \(k-\varepsilon\) model, the realizable \(k-\varepsilon\) model, the standard \(k-\omega\) model and the shear-stress-transport \(k\)-model. It has found that the realizable \(k-\varepsilon\) turbulence model usedwith enhanced wall functions and near-wall modelling techniques, consistently provides superior performance in predicting the flow characteristics around the hydrofoil.
