Submersible Stereo PIV - Dantec Dynamics

Submersible Stereo PIV in towing tank

Measurements in towing tanks and other underwater applications

Our submersible stereo PIV (2D3C) solution enables efficient flow-field measurements in towing tanks and other underwater applications. The solution is used world-wide for research on hydrodynamic applications such as ship hulls, propellers, and offshore constructions.

The system comes with a modular watertight and streamlined probe for minimum flow disturbance. The system is optimized for easy mounting and dismounting, fast calibration, and efficient use of the experimental time.

In combination with a traverse and a rigid fixture of the probe, the system can be moved while maintaining alignment and calibration. The entire system – traverse, camera arrangement (remote controlled), calibration, automatic measurements and analysis – is operated/performed from our dedicated software suite, DynamicStudio.

Measurement Principle

Particle Image Velocimetry (PIV) is a whole-flow-field technique providing instantaneous velocity vector measurements in a cross-section of a flow.
