This paper mainly proposed a dynamic control method of particle distribution uniformity in a rolling circulating fluidized bed (RCFB) by using an air distribution plate. An Euler–Euler numerical simulation approach which is called two-fluid flow model is used to simulate the behaviors multiphase flow within the RCFB. Six different tilt angles θ which are θ = 2°, 5°, 8°, 10°, 12° and 15° are used for the fixed inclination state of the RCFB, meanwhile, eight different inclined angles φ which are φ = −2°, −5°, 0°, 2°, 5°,8°, 10° and 12° are used for the location of the air distribution plate. After performing the simulation, the following three different conclusions are obtained. Firstly, with the increase of θ, serious uneven distribution behaviors for particles are founded at the lower position of the riser which is a part of the RCFB. Secondly, by adjusting φ, the uneven phenomenon of particles distribution behaviors is able to be alleviated no matter how θ changes for the RCFB. Thirdly, a function relation between θ and φ is obtained, which is verified by using the dynamic control method based on the dynamic mesh model in the RCFB.

本文主要提出一种利用空气分配板动态控制滚动循环流化床中颗粒分布均匀性的方法。一种称为两流体流动模型的Euler-Euler数值模拟方法用于模拟RCFB中的多相流动行为。六个不同的倾斜角θ，其是θ  = 2°，5°，8°，10°，12°和15°被用于RCFB的固定的倾斜状态，同时，八个不同的倾斜角φ，其是φ  = -2 °，-5°，0°，2°，5°，8°，10°和12°用于空气分配板的位置。执行模拟后，获得以下三个不同的结论。首先，随着θ的增加，在作为RCFB一部分的立管的下部位置，发现了严重的颗粒不均匀分布行为。其次，通过调整φ，无论RCFB的θ如何变化，都可以缓解颗粒分布行为的不均匀现象。第三，得到θ与φ之间的函数关系，并通过基于RCFB中的动态网格模型的动态控制方法进行验证。
