摘　　要：应用三维LDA对同向射流模型燃烧室的流场进行测量,对结果进行了分析。应用k-ε湍流模型进行了数值计算,计算结果与实验结果在定性上是一致的。A new type of pulverized coal precombusti on chamber using coflowing jets .with large velocity difference's has been developed and applied to utility boilers in China since the early eighties. The f lowfields of a model chamber were measured with a 3-D LDA system. The results are presented and analyzed. In addition, numerical computational results are given and are shown to be in qualitative agreement with the experiments.
