An experimental and numerical study of the injection of liquid jets in subsonic gaseous crossflows was conducted. The focus of the study was on spatial size distributions of this type of atomization in different flow conditions. An experimental setup was developed to characterize the spray in conditions similar to real applications. The test chamber developed enabled the use of various spray characterization techniques by providing optical access from four sides of the spray. This allowed for size and velocity measurements of the spray using various laser diagnostic techniques such as PDPA, IPI and PIV. Also, a model was developed to predict the size distribution of the spray downstream of the nozzle. This model is based on combining both theoretical calculation of a jet in crossflow and a modified KIVA3 numerical code.
