Talk Title: Study on Two-Phase Velocity Field of a Steady Hydraulic Jump Using PIV and BIV
Abstract:
A hydraulic jump is widely used as an energy dissipator and is commonly seen in channel flows downstream of a spillway or sluice gate. The kinematic structure of a hydraulic jump is very complicated because of the violent turbulent mixing and air entrainments in the jump. It has confronted many investigators for several decades.
By employing both the BIV (Bubble Image Velocimetry) and PIV (Particle Image Velocimetry) Professor Lin and his research group have successfully obtained the flow structure in the aerated region of a steady hydraulic jump using BIV and the flow structure outside the aerated region using PIV.
The experimental techniques to be presented will have wide ranging applications for wave breaking studies in coastal engineering as well as investigations on bubble flows for waste water treatment in environmental engineering field.
