| description abstract | To protect hydraulic structures such as spillways, chutes, and bottom outlets against cavitation damage, air is normally added by means of aerators in regions where the cavitation number falls below a critical value. Although aerators have been investigated for more than 30 years, the current design methods for aerator spacing are not reliable. The detrainment process was not previously investigated in detail because of limited laboratory instrumentation. The research presented in this paper provides new model data for hydraulic chutes of variable bottom slope. An advanced remote-controlled, fiber-optical instrumentation was employed to investigate the streamwise development of air concentration contours, velocity contours, and air bubble size along a | |
