摘要
应用多尺度能量最小理论对循环流化床Siegen流体动力学模型进行了改进，加强了模型理论基础的一致性，增加了模型的解析性。建立了空隙率轴向分布和上、下行固体质量流量计算的新方法。改进的模型预测值与文献报道的实验数据吻合一致。
By employing the Energy-Minimization Multi-Scale (AMMS) model, Siegen's modelfor the hydrodynandcs in a CFBC was improved. Based on the underlying mechanism, a new method to calculate axial voidage profile, upward and downward solid mass flux is proposed, which strength ens the uniformity of theoretical background of the model and makes it more analyticable. The comparisons between model predictions and experimental data indicated that the model is capable to describe the hydrodynamics in a CFB.
