An analytical model for vortex at vertical intakes | Water ...
Aug 31, 2021· One important case in engineering practice is withdrawing water at intakes. Surface vortex formation at intakes is an undesirable phenomenon, causing air entrainment into the intake, vibration and energy loss (Knauss 1987).Vortices can be divided into six types based on visual classification at the Alden Research Laboratory (Padmanabhan & Hecker 1984).
