Abstract
Complex flows over a drop with a trench in which supercritical and subcritical flow coexist, have b en computed by a low Reynolds number k-ω turbulence model and the standard k-ω model. The k-ω model predicts the free-surface shape, separation area and the turbulent kinetic energy and shear stress distributions in both test cases consistently well, while k-ω model fails to reproduce the case of supercritical flow over and past the trench. The calculation results imply that complex flow over the drop and trench cannot be represented properly by the method that relies on the wall function boundary condition.
