A three dimensional particle-splitting model for atmospheric dispersion
三维大气扩散粒子分裂(ADPS)模式

A Three-Dimensional Particle-Splitting Model for Atmospheric Dispersion (ADPS Model) which is based on the PIC method is described and tested with the analytical solutions and the data obtained in Guangzhou region in 1988 . The model introduces the nested grid capability and big particle definition , puff diffusion theorem and particle-Splitting technique under the assumption of the local time-independent and local spatial uniform. The model is used to simulate atmospheric dispersion of gaseous pollutant and also has the ability to simulate the TSP dispersion .
