| Abstract: | A framework of two phase turbulent model of particulate matter (PM) in health and flue of coal-combustion-boiler was formed. Such physical and chemical process as particle collision, coagulation, coalescence, nucleation, break-up, chemical reactions, and so on were included. The idea and method of the model forming were put forward, the emphases and key point were listed out, the number density function of particle was given. These will provided a basis for flowing simulation of PM. |

| Keywords: | coal combustion particulate matter probability density function Reynolds stress model particle number density function |
