摘要
利用三维粒子动态分析仪(PDA)测量了流化床冷态模型中的三维粒子速度,测量了循环流化床内的湍流能量,也对粒子的轴向空隙率进行了测量.实验结果证明了循环床的环一核流动结构的存在,也对循环流化床的气动力特性提供了有价值的数据.
The three-dimensional particle velocity in a CFB cold model, the turbulent flow energy in the CFB and particle vertical voidage are measured with a three-dimensional particle dynamic analyzer (PDA). The results obtained demonstrate the existence of the annular-core structure in CFB and provide valuable data on the aerodynamic characteristics of CFB.
