摘要
对Geldart B、D类颗粒进行了射流深度计算关联式的研究。对前人的实验数据进行多元线性回归分析,建立了射流流化床中Geldart B、D类颗粒射流深度的计算关联式,关联式计算值与实验值吻合较好。将关联式与其他研究者得到的关联式进行比较,本关联式误差相对较小。
Various measuring methods were reviewed in this paper. The effects of particle diameter, particle density, nozzle diameter, jet gas velocity, and static bed height on penetration depth were discussed in detail. The Geldart group B and Geldart group D particles were studied experimentally. Based on analyses of the experimentation data, two correlations for predicting the jet penetration depth of different particles were developed. Calculation data of the correlation are in agreement with the experiment data.
