The Coherent Structure of The Turbulent Meandering Flow with Flood Plain

The coherent structure of the turbulent meandering flow with flood plain are investigated using a nobel visualization technique that utilizes fluorescent dye excited by a sheet of halogen light and black lamp. Some of new aspects of reversional spiral flow in corner region, especially with respect to pattern of existence, structure, behavior and formation are infered from this experiment. The results indicate that a lot of various coherent structures are formed in the turbulent meandering flow with flood plain. The coherent structures are characterized by the interaction between main flow and the local flow influenced by some boundary conditions of the turbulent meandering flow with flood plain.that a lot of various coherent structures are formed in the turbulent meandering flow with flood plain.
