Theoretical and experimental study on the vortex at hydraulic intakes
To study the characteristics of the vortex at a hydraulic intake, an experiment with a free surface vortex was conducted in a cylindrical tank. The vortex flow field was measured using particle image velocimetry (PIV) and extensive experimental data describing the vortex characteristics (radial and tangential velocity distributions, vortex core radius variation, water surface profile and circulation distribution) have been obtained and analysed. Based on the detailed experimental data, an empirical model describing the key vortex characteristics is developed. In addition, using the pressure distributions inside and outside the vortex core, a dimensionless equation for the critical submergence requiring only the Froude number and the circulation number is derived. Results using this equation are in agreement with the experimental data.
