Abstract:

In the paper, the structure of flow is investigated using fractal scaling of 3-D velocity fluctuations and the Reynolds shear stresses around a bridge pier. The fractal dimensions were computed using a Fractal Interpolation Function algorithm. The velocity data were collected in a series of experimental test within a laboratory flume. Three dimensional velocity fluctuations were measured at a number of grid points around a bridge pier using an Acoustic Doppler Velocity meter (Micro-ADV). At each point, 6000 velocity samples were captured at a frequency of 50 Hz. The statistical analysis of fractal dimension shows that the average fractal dimensions reduced from centreline of the flume to the wall, but standard deviations of fractal dimensions increased significantly in the longitudinal and transverse flow directions in the vicinity of the pier. © 2012 Taylor & Francis Group.
