Effervescent atomizer - temporal and spatial variations of spray structure
Original language description
An effervescent atomizer generated spray is studied using combined PIV-PLIF technique. Liquid phase concentration, 3D velocity and thus mass flux distribution in a plane perpendicular to the spray axis is measured. Spatial and temporal fluctuations of the liquid concentration and mass flux are evaluated. Both fluctuations show annular spatial distribution with low value near spray axis and maximum close to the spray edge. A transparent Plexiglass atomizer is used in this study. Internal atomizer two-phase flow patterns are predicted by published maps and actual two-phase flow structure is visualized by a digital camera. The atomizer is operated in the range of air gauge pressure 0.1 - 0.5 MPa and Gas-to-Liquid-Ratio 2 - 50%. This range of operation conditions leads to various two-phase flow patterns from bubbly to dispersed. Results show that in case of high GLR the internal mixture is relatively homogeneous and decreasing GLR under certain value can lead to a poor mixing. Influence of
