Resumo
The paper studies the process of liquid atomization in high-speed gas jets with application to a subject of high-rate fuel nozzles. Experiments were carried out for gas-liquid jet with the central-axis feeding of liquid to the outlet of a confuser-type nozzle with pumping of air in subsonic and supersonic flow regimes. The energy balance approach was developed for describing a gas-liquid jet. This provided us the needed data for comprehensive description of the gasliquid jet: gas velocity field without liquid, shadow visualization of geometry and wavy structure of a jet with liquid and with pure gas, velocity profiles for liquid phase, spray droplet size, spray concentration and spatial distribution. The gas-liquid flow was characterized by Weber number from the time of liquid jet breakup till the final spray.
