Characterization of flow turbulence in mobile boundary channels
An experimental investigation on measurement of 3-D instantaneous velocity profiles in a mobile boundary channel with uniform and non-uniform sediments are reported. The estimated velocity fluctuations from measured velocity profiles along the center line of the flume are used to quantify the nature of bursting events, and turbulence characteristics on uniform (finer and coarser) and non-uniform sediments. The analysis presented in the paper indicated that sediment characteristics play very significant roles for existence of aforesaid characteristics (turbulence characteristics and bursting events) near the channel beds and fluid flow regions in the main flow. Further investigations on aforesaid theme are recommended, while taking the measurements on velocity profiles along the depths across the channel width including the center line depth of the channel.
