Abstract

PTV (Particle Tracking Velocimetry) is used to investigate the turbulence structure in a narrow rectangular open channel. Instantaneous velocity fields are measured by a visualization technique. As the result, spatial distribution of the two-dimensional divergence and the vorticity are also shown. It is recognized that the mutual relationship among these quantities of the time-averaged distribution is strongly affected by the secondary-flow in an outer region of the transverse cross-section in the channel.
