| 摘 要： | 对混合悬浮混合排料(MSMPR)连续结晶器的定态方程组进行了剖析,应用非线性方程组的延拓求解法,求得了定态方程组的分岔图,即MSMPR连续结晶器状态参数与操作参数的依赖关系.利用分岔理论对MSMPR连续结晶过程的定态数目及相应的参数范围进行了预测,导出了连续结晶过程存在多定态或唯一定态的判据。该判据仅与过程的动力学参数和操作参数有关,而与过程的状态参数无关。最后应用Routh-Hurwitz准则,确定了连续结晶过程各定态的稳定性。

| Abstract: | The bifurcation diagrams of state variables versus operation parameters for a continuous isothermal mixed - suspension, mixed - product removal (MSMPR) crystallizer have been obtained by resolving the steady state equations with the continuation technique of nonlinear equations. The number of steady states of the continuous MSMPR crystallization process for various multiplicity regions is determined and the criteria of multiplicity(i. e. , multiple steady states) and uniqueness, which is only dependent of the kinetic properties and operation parameters of the crystallization process, is developed by the use of bifurcation theory. In addition, the stability of steady states is analyzed by using the Routh - Hurwith criteria. |
