Particle Image Velocimetry

Particle Imaging Velocimetry Device for MCR: PIV

Most rheological theories are based on the assumption that a laminar flow field is present during the measurement. However, in practical applications samples also show a turbulent flow field. The visualization of flow fields is of great importance in hydrodynamics or the investigation of mixing procedures. Particle Image Velocimetry (PIV), sometimes also called Particle Tracking Velocimetry (PTV), simultaneous to rheological tests is therefore a useful tool for investigating complex flow fields such as shear banding, turbulence or flow instabilities.
