A new experimental procedure for performing simultaneous, phase-separated velocity measurements in two-phase flows is introduced. Basically this Particle Image Velocimetry (PIV) technique is a combination of the three most often used PIV techniques in multiphase flows: PIV with fluorescent tracer particles, shadowgraphy and the digital phase separation with a masking technique. In order to combine the advantages of these multiphase-PIV methods a new PIV setup was developed. With this setup the velocity distributions of the two phases are measured simultaneously with only one b/w camera. This experimental set-up is aimed at providing a means for characterizing the modification of turbulence in the liquid phase by bubbles, this phenomenon is often called “pseudo-turbulence” (van Wijngaarden, 1998).
