Effervescent Atomizer: Influence of the Operation Conditions and Internal Geometry on Spray Structure; Study Using PIV-PLIF

Popis výsledku v původním jazyce

A single-hole effervescent atomizer spraying light heating oil (LHO) with air as an atomizing medium in the outside-in gas injection configuration is studied. Influence of operation conditions and atomizer design parameters on spray structure is described. Inlet air gauge pressure and gas-to-liquid-ratio by mass (GLR) are varied. Several design parameters are modified: size and number of aeration holes, their location, diameter of the mixing chamber and shape of discharge orifice. 2D velocity field of droplets in the spray and distribution of liquid phase concentration in the plane of the exit orifice axis are evaluated using PIV-PLIF. Results show relatively small influence of the atomizer design on droplet velocity profile and on the concentration distribution. Droplet velocity and concentration data is used for calculation of mass flux and resulting spray cone angle The spray cone half-angle has a value in the range 6.5 to 9.3 deg for all measured configurations and operation condit
