【摘要】 从稀相区的湍流扩散机理出发 ,推导并建立了涉及到密相区气泡运动规律、弹溅区规律及稀相区颗粒运动规律的 TDH计算的新模型 ,进一步在一套 870 m m× 110 0 0 mm / 710 mm× 4 0 0 0 m m大型有机玻璃湍流流化床中对所建立的模型进行了实验检验。检验结果表明 ,模型的计算结果与实验数据吻合较好更多还原

【Abstract】 Based on the mechanism of turbulence diffusion,a new model for TDH at the freeboard was established This model concerned the behavior of bubbling motion in the dense phase region,splashing height and particle motion at the freeboard By using a large size turbulent fluidized bed of plexiglass with dimension of 870mm×11000mm/710mm×4000mm,it is found that experimental results are in good agreement with the developed model for TDH更多还原
