| 摘 要： | 基于颗粒絮团更新理论和对气膜热阻加以修正的方法,提出了絮团停留时间关联式,进而通过求解一维非稳态导热方程得到了快速床壁面换热模型。用三位作者已发表的数据代入模型进行计算的结果表明,模型对换热系数的预测值与实验值的偏差较小,证明模型是合理的和可用的。

| Abstract: | A model was developed to predict the efficiency of heat transfer in CFBsbased on the theory of cluster renew and the method of modifying the heat re-sistance of gas-film. The reasonableness and usability of the model were verifiedby using experimental data obtained by three authors into the model. |
