Turbulent flow mechanisms in meandering channels with sediment transport

Abstract This research aims to investigate the near-bed turbulent flow characteristics in a meandering channel with both mobile bed and immobile conditions. Experiments were performed prismatic rectangular non-uniform sand of size d50 = 0.523mm. The three-dimensional instantaneous fluid velocity was collected using Acoustic Doppler velocimeter which will provide important results related turbulence such as mean velocity, intensity, Reynolds shear stress, kinetic energy, skewness, kurtosis anisotropy. secondary current exchange momentum form stress intensity at inner layer are identified more condition compared an condition, causes sediment transport. For flow, energy decreased magnitude gradually increase outer for Higher anisotropy is noticed than shows nonuniformities near level condition. study may help understanding effect transport due structure sinuous alluvial channel.
