RESUMO

PIV applications for non-combusting and combusting spray were investigated by an industrial oil burner of 0.1 MW. An optical parameter and signal-processing scheme are examined to have optimum set-up. Phase Doppler technique was used to evaluate the PIV data. Size classified technique was also implemented. The results show that non-combusting PIV can demonstrate well the 2 dimensional droplet vector map of 20-30 µm and combusting PIV could show whole field velocity vectors of medium size droplet of 5-30 µm. The spatial structure of combusting spray was measured by this PIV.
