| Abstract: | This paper describes and evaluates the techniques for simultaneous measurementsof velocities, particle size and concentration in two-phase flows by means of a Laser-DepplerVelocimetry(LDV)of a Phase-Doppler Particle Analyzer(PDPA). The time series measurementsof the particle size and velocity by a PDPA are also presented in order to analyze the local dynamictwo-phase ffow structrue. |
