We performed Large-eddy simulations (LES) of the flow around a low-aspect-ratio wall-bounded 2D hydrofoil at the zero angle of attack using spectral-element method (SEM). The flow was considered for several Reynolds numbers Re_C = 500, 5.0 × 10³, 5.0 × 10⁴ and 1.2 × 10⁶ based on the foil chord to reveal the influence of the test channel sidewalls and viscous effects. The laminar-turbulent transition of the boundary layer was registered. A comparison of the numerical results with experimental data for the highest Reynolds number was performed and showed an excellent agreement.
