三相流化床的流动特性预测

Prediction of Characteristic of Hydrokinetics in Three phrase Fluidized Bed Reactor

在１ｍ塔径三相流化床冷态试验基础上，采用因次分析和相似准则对试验数据进行处理，得到一种用相似准数关联的三相流化床流动特性预测模型．比较分析表明，此模型具有较好的预测准确性，可用于不同塔径三相流化床流动特性的预测，为三相流化床的工业放大提供指导．

On the basis of cold test of three phrase fluidized bed with the diameter of one meter,the test data are processed by using dimensional analysis and similarity criteria.And a predicting model with similarity criteriais gained,to predict charactreistics of hydrokinetics in three phrase fluidized bed reactor.It is shown by the analysis and comparison that this model has fairly good predicting accuracy and can be used to predict characterisitic of hydrokinetcs in three phrase fluidized bed for the case of different reactor's diameter.The model will provide guidance for industry amplification of three phrase fluidized bed reactor.
