The Turbulent Flow Fields and Vortex Structures Inside Surf Zone
In order to understand the characteristics of turbulence due to wave breaking, flow visualization techniques are used to observe the external and internal flow structures. Two typical spilling and plunging breakers are made in wave flume. 2W Argon-Ion laser, and 120W ultraviolet lamps are used to brighten the tracing particles respectively. In this situation, not only the external structures of wave breaking can be visualized but also the instantaneous velocity of particles in the internal flow field will be outlined. Moreover, it is valuable to point out that the three dimensional flow structures inside surf zone are also found in our elaborated experimental studies.
