An incompressible, isothermal turbulent water flow in a square cross-section curved duct was investigated numerically. The duct had a 90-degree bend. The numerical simulations were conducted with different turbulence models (k-ε, k-ω, Shear Stress Transport and Reynolds Stress SSG). The ANSYS CFX code was used for all computations. The obtained results were compared with the measurements reported in literature.
