针对循环流化床内颗粒自转是否对流化状态产生影响这一众多研究者所关心的问题 ,用离散数值模拟方法首次对该问题进行了研究探讨 ,研究发现 ,无论颗粒是否自转均有聚团产生 ,但对床内的空隙率分布造成影响 Aiming at the question concerned by many researchers whether the rotation of the particles in the circulating fluidized bed affects the fluidization state, this problem was studied for the first time by using the discrete numerical simulation method. It is found that the particles are agglomerated regardless of whether the particles rotate or not , But affects the distribution of void content in the bed
