Abstract
The collection of fine experimental data is a constant need for the validation of CFD codes. The experimental techniques currently applied in hydrodynamic test facilities for the measurement of 3D velocity fields are generally intrusive (Pitot tube, propeller-type flow meter, hot wires) and/or time and resource consuming (Laser Doppler Velocimetry). In this context, the Particle Image Velocimetry (PIV) is very interesting since it is non intrusive and it delivers data over a plane at each measurement. Two component PIV systems, delivering the two in-plane velocity components, already exist and start to be used in basins. However, their range of application remains limited. They cannot operate correctly in tri-dimensional flows, which are generally encountered in basins (by nature, such as behind propellers, or because of the forward speed of the model). In this context SIREHNA just acquired a new three component PIV (3C-PIV) system, specifically designed for tests in hydrodynamic basins. This system is rugged, mobile and adapted to both research and industrial tests
The present paper describes this new measurement system and presents examples of measurements collected during tests performed for the Maritime Research Institute of Netherlands (MARIN) in the frame of the Leading Edge EU project.
