| 摘 要： | 从近年来气固流化床两相流动的研究成果出发,总结了流化床非线性机理研究的方向.混沌理论研究表明流化床系统是确定型的混沌系统,而耗散结构理论的结果认为流化床系统属于非平衡热力学系统.对流化床系统的随机力分析将随机理论的方法运用到流化床流动机理和气泡分布研究中,有助于揭示流化床内部非线性机理和特性.

| Abstract: | Recent studies on two phase flows in gas-solid fluidized beds were retrospected, and the development in nonlinear mechanism studies was outlined. The chaos studies indicate that fluidized bed systems are determinacy chaos systems and the results of the dissipative structure theory attribute fluidized bed systems to non-equilibrium thermodynamic ones. The analyses of stochastic force on fluidized bed systems apply the stochastic theory to flowing mechanism and studies of bubble distribution, and redound to open out the inside nonlinear mechanism and characteristic of fluidized beds. |
