Abstract:

© 2012 Engineers Australia. The detailed study of three dimensional flow structures around two bridge piers is presented in this paper. Eight sets of laboratory experiments were carried out with no pier, a single pier and two piers with different spacing between piers. Two bridge piers were aligned in the direction of flow and at the centre of a laboratory flume. The experimental tests were performed in a flume with 19 m length, 0.61 m wide and 0.60 m deep, under different flow conditions. Three dimensional flow velocities were captured at different grid points and different depths within the flow using a micro Acoustic Doppler Velocimeter (ADV). The velocity was captured at a frequency of 50Hz. The contour plots of three velocity components, turbulence intensities, Reynolds shear stresses and the turbulence kinetic energy as well as the vector plot and flow streamlines were presented in this paper. It was found that significant flow structure interactions are generated with increasing the spacing between the piers. In addition, the results indicated that the flow structure between the piers and at the downstream side of the piers varied significantly. Furthermore, it was found that when the spacing between bridge piers is increased, the effect of the upstream pier starts decreasing and eventually each piers act as an individual pier.
