| Abstract_FL | In order to solve the problem of low gas-liquid separation efficiency of singlet oxygen generator,a generator with spiral blades for high-velocity centrifugation of atomized droplets is designed.The separation performance of the reaction zone is numerically simulated based on computational fluid dynamics method.The three-dimensional model of the generator and flow field is built by using Creo,and the model is numerically simulated using the combination of multiple reference frame(MRF)model and discrete phase model(DPM)in Fluent software.For the systematic simulation under different structural parameters,operating parameters and physical property parameters,the flow field distribution of the continuous phase and the characteristic curve of the moving particles of the discrete phase under different parameters are obtained,and the research shows that the generator can achieve more than 90％of separation efficiency for the droplets of 20 μm and above particle diameter at the rotating velocity of 2 000 r/min. |
