THE KINEMATICS OF WAVE INDUCED FLOWS AROUND NEAR-BED PIPELINES

T. Bruce, W.J. Easson

Abstract


Particle Image Velocimetry (PIV) has been applied successfully to give quantitative, full field measurements of instantaneous velocity fields for oscillatory flows past a model of a pipeline above a plane bed. The application of PIV to this problem is discussed, and results for the case of KC = 20 with gap ratios 1.0 and 0.1 are presented in the form of velocity vector maps, and contour plots of vorticity distribution.
