The investigation of complex flow fields such as shear banding, turbulence, or flow instabilities is of great importance in hydrodynamics or the analysis of mixing procedures. 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 via digital Particle Image Velocimetry (PIV), sometimes also called Particle Tracking Velocimetry (PTV), simultaneous to rheological tests is therefore essential.
