Paper Abstract

A 3D measurement is presented of both the in-plane and out- of-plane components of the flow field velocity of 0.5 micrometers styrene particles at 30 ms-1 in air from a calibrated nozzle by using a co-linear side scattering PIV approach. The light sheet used to illuminate the particles was generated using a Nd:YAG laser, operating in triple pulse mode. The scattered light from the particle was imaged through a near diffraction limited lens. The particle images have been analyzed 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 micrometers .
