Abstract EN
The paper refers to the numerical analysis of the internal flow in a hydraulic cross-flow turbine type Banki.
A 3D-CFD steady state flow simulation has been performed using ANSYS CFX codes.
The simulation includes nozzle, runner, shaft, and casing.
The turbine has a specific speed of 63 (metric units), an outside runner diameter of 294 mm.
Simulations were carried out using a water-air free surface model and k-ε turbulence model.
The objectives of this study were to analyze the velocity and pressure fields of the cross-flow within the runner and to characterize its performance for different runner speeds.
Absolute flow velocity angles are obtained at runner entrance for simulations with and without the runner.
Flow recirculation in the runner interblade passages and shocks of the internal cross-flow cause considerable hydraulic losses by which the efficiency of the turbine decreases significantly.
The CFD simulations results were compared with experimental data and were consistent with global performance parameters.
