title = "Visualization of large flow structures at the free-surface of an open channel flow",
abstract = "The heat produced at the water surface by infrared (IR) radiation and subsequent cooling is used as a tracer to infer characteristics of the large flow structures in an open channel flow. These large flow structures, labeled large streamwise vortices, are visualized at the free surface through the use of an IR video camera during the cooling period. The upwelling regions cool more rapidly than the downwelling regions. The location of large flow structures may be identified because of the upwelling and downwelling character of these flow structures. The length scales of the large flow structures are compared to the scales of the flow field. Copyright ASCE 2004.",
