A Three dimensional measurement is presented of both the in-plane and out-of-plane components of the flow field velocity of 0.5 mu m styrene particles at 30 ms(-1) in air from a calibrated nozzle by using a co-linear side scattering PIV (Particle Image Velocimetry) approach. The light sheet used to illuminate the particles was generated using a Nd-YAG laser (200mJ), operating in triple pulse mode. The scattered light from the particle was imaged through a near diffraction limited lens. The particle images have been analysed from both their respective diffraction patterns and from their out of focus intensity profile. The authors show that the co-linear 3D PIV method can be used to determine the particle velocity in three directions.
Results have been presented for different flow angles through a calibration 30ms(-1) air jet, showing that it is possible to identify the particle position in three directions, within a turbulent flow, to a spatial accuracy of +/-20 mu m.
