THE IMPROVEMENT OF THE PARTICLE RANDOM TRAJECTORY MODEL

颗粒随机轨道模型在应用上的改进孙保民，徐旭常（清华大学热能工程系北京１０００８４）关键词随机轨道模型，数值模拟，锅炉１引言颗粒随机轨道模型由于能够详细模拟多相流中有复杂经历（如蒸发、挥发和异相反应）的颗粒相，并能形象地反映颗粒随机脉动物理现象，近年来...

The random trajectory model for modeling the pulverized coal particle motion and its course of variation is widely used in numerical calculation of coal combustion. However, some defects of the model were discovered and the improvements on the model have been made. The numerical calculation of the motion and combustion of PC particle in W-shape flame boiler was made by the model improved and some beneficial results have been achieved.
