Arithmetic Research on GDE of PM10 Turbulence Coalescence and the Example Analysis

GDE has been proved to be one effective method for the simulation calculation of the ultrafine particle coalescence situation. Many methods were explored, including the Partition algorithm, the Moment method, the MC method and so on. The initial size distribution of the PM10 was measured using the laser particle size analyzer and the ANDERSON, which provided a theoretical basis for the ultrafine particle coalescence numerical simulation. Using CFD software, the turbulence coalescence model was established. The results were consistent with the literature and experiments, which illustrated the rationality of the turbulence coalescence and arithmetic method effectively.
