Abstract

Particle tracking velocimetry measurements to assess the performance of flow control structures R. Crowded, B. Hofland^, R. Kirby^ *Bullen Consultants, UK * Department of Civil Engineering, TU Delft, Netherlands ^Revensrodd Consultants, UK Abstract Particle tracking is a well practiced and understood method of visualising flow and calculating vector fields. It is based on the assumption that floating particles on the water surface precisely follow the fluid motion. By taking time lapse images/photographs of floating particles streamlines can be visualised and vector fields generated. Historically these have been analysed manually. This is a labour intensive exercise, prone to mistakes and inconsistency. In this study low density Particle Tracking Velocimetry (PTV) has been utilised to assess the performance of an array of Flow Control Structures placed at the entrance of a harbour basin to reduce the mass afflux and hence the sedimentation rate within the basin. The technique det
