Abstract:
Air-intake filters can filter out salt aerosols in the ocean atmosphere, which plays a key role in improving quality of air intake for marine gas turbine. To carry out precise experiment study on air-intake filters for gas turbine and its improved design, ocean atmosphere simulating in laboratory conditions is needed. Thus, an artificial seawater spray chamber with spraying nozzles is designed to produce aerosols, which is similar to salt aerosols in real ocean atmosphere. Droplet concentration uniformity is an important indicator to measure performance of artificial seawater spray chamber. In this article, experimental method and CFD technology were both used to explore impact of nozzle performance and arrangement on droplet concentration uniformity in the spray field. To obtain more accurate numerical simulation data, an experiment was carried out before simulation to measure atomizer angle and particle size distribution of the spray, which will be used in real artificial seawater spray chamber. Experiment data was taken into CFD software, set as the initial boundary conditions. In the numerical simulation, changing number and arrangement of nozzles, gas-particle two-phase flow field in different schemes have been calculated. Those data can be used as references in designing real artificial seawater spray chamber.
