Dynamic Behavior of Chemical Reactors

PI建议通过研究非稳态行为来继续他对控制化学反应堆动态行为的基本原理的研究。他的目标是深入了解化学过程，并将结果用作促进对化学动力学的理解的范例。他计划研究两个系统：电化学过程和两阶段过程。金属电溶解动力学的模拟可以有多种形式：一种方法是用从电极表面反应导出的常微分方程式模拟该过程，而另一种模型的固有性质是通过电极表面的膜进行扩散。PI计划考察这两种类型的模型，并通过实验确定最好的一种。他还计划研究除金属溶解以外的电化学反应的动力学，例如电化学催化反应。还将研究气液连续化学反应器系统的动力学。反应发生在液体中，其中一种反应物，通常是氧气，从气相中被吸收。PI计划研究反应对传质速率的影响，从而研究强化传质与振荡行为的相互作用。将对数学模型进行假设，然后进行实验验证。

The PI proposes to continue his investigations into the underlying principles that govern the dynamic behavior of chemical reactors by studying unsteady state behavior. His objectives are to gain insight into chemical processes and to use the results as paradigms with which the understanding of chemical dynamics can be advanced. He plans to look at two systems: electrochemical and two-phase processes. The modelling of the dynamics of electrodissolution of metals can have various forms: one approach is to model the process with ordinary differential equations derived from surface reactions on the electrode surface while other models have as an intrinsic property the diffusion through a film on the electrode surface. The PI plans to look at both types of models and experimentally determine the best one. He also plans to look at the dynamics of electrochemical reactions other than metal dissolution such as the electrochemical catalytic reactions. The dynamics of gas-liquid continuous chemical reactor systems will also be studied. Reaction occurs in the liquid phase and one of the reactants, normally oxygen, is absorbed from a gaseous phase. The PI plans to investigate the effect of reaction on the rate of mass transfer, and consequently, the interaction of enhanced mass transfer with oscillatory behavior. Mathematical models will be postulated and then experimentally verified.
