Аннотация: The results of the modeling of unsteady three-dimensional flows in the hydroturbine ducts of two high-head hydroelectric stations are presented. The flow structure behind the turbine wheel is analyzed and its effect on the frequency and the intensity of unsteady processes in the duct is shown. The individual features and the general tendencies in the behavior of the fluctuation characteristics of both turbines are established.
