Bubble Measurements Downstream of Hydraulic Jumps

  • Tricia A. Waniewski Christopher Hunter Christopher E. Brennen


A phase Doppler anemometer (PDA) system was used to measure the velocity profiles and air bubble size distributions downstream of two-dimensional hydraulic jumps for different upstream flow conditions in a 1.92 m long laboratory flume. The PDA detected bubbles from 1 to 500 μm in diameter, and more were found at the bottom of the downstream flow near the… (More)
