摘　　要：建立并发展了基于颗粒相连续介质—轨道模型的煤粉燃烧数学模型，并相应发展了一种有反应两相流的总体选代算法，自行编制了计算二维湍回流有反应两相流的通用ＬＥＡＧＡＰ程序。A mathematical model of pulverized coal combustion is formulated and developed based on a particle continuum trajectory model.An overall iterative solution procedure for reactive two phase flows is also proposed.The corresponding CCVC computer code has been developed for calculating two dimensional, recirculating,reactive,two phase turbulent flows.It is utilized to numerically simulate the pulverized coal combustion in a combustor of large velocity difference jets which at plesent is widely used in coal fired boilers.
