摘　　要：该文给出一种用于强旋流的气固两相湍流模型，采用双流体模型及相应的数值解法，求解旋风炉燃烧室内气固两相流动及煤粉燃烧。模拟结果表明：前置室内湍流空气动力场分布具有强旋、中心回流和各向异性湍流的特点。Abstract In this paper, a gas solid two phase turbulence model is given to calculate strongly swirling flow. Two fluid model is used to simulate gos solid two phase flow with pulverized coal combustion. The results of modeling show that the flow in cyclone furnace combustors prossesses the properties of strongly swirling, reverse flow and anisotropic turbulence.
