Dynamics of Drop Formation during Filtration through a Porous Body

This paper presents the study of characteristics of porous rotating nozzles recommended for use in gas cleaning devices. The influence of geometrical and technological parameters of atomizer on the size of droplets and the trajectory of their motion is investigated theoretically and experimentally. To determine the droplet size when it is detached from the spherical granule of porous rotating atomizers (PRA), the simulation in the Flow3D program was used. A model for calculating the droplets trajectories when spraying a liquid with the help of porous rotating nozzles is compiled. The model is based on a joint solution of equations of droplet motion in a centrifugal field and evaporation of droplets. The relationship between the volume of separating droplets and the size of granules of porous material and the geometry of atomizer is obtained. The regularities of droplet motion in cylindrical devices with porous rotating atomizers are established depending on the droplets sizes and parameters of the cross-flow. The relationship between parameters of droplets’ trajectory and their volume is recommended for calculating the geometry of the spray torch of PRA in gas cleaning devices.
