Abstract: Measurements of turbulence characteristics are crucial to the study of bend flow. This paper presents detailed measurements of instantaneous 3D velocity at various cross-sections in consecutive bends by using a three-dimensional (3D) electromagnetic current meter. Details of turbulent flow characteristics in the bend were obtained, including turbulence spectrum, turbulence intensity, turbulent shear stress, etc. It is found out that turbulence energy is mainly carried by fluctuations below 10Hz. Turbulent flow characteristics are closely related to secondary current.
