It is proposed to apply the chaos theory to mixing of particle systems, without and with an interstitial liquid, and to develop and experimental approach to quantify the mixture performance in a simple flow configuration. Mixing of particle systems is significant different from mixing of fluids due to the segregation and secondary phenomena caused by interparticle interactions. Even if mixing plays an important role in chemical, petroleum, mining and pharmaceutical processes, no reliable theory with a larger range of generality has been developed. The proposed approach offers a sound background for developing a chaos based theory, and a simple device for model calibration and testing. Several technological improvements are expected by the introduction of various disturbances which would enhance mixing of particulates. The research project to be focused on the differences between single fluid mixing and particulate mixing, and on the generic aspects which can be obtained from the experiments on the proposed device. The feasibility of the chaos theory applied to particulate mixing is a main goal of this project.

提出了将混沌理论应用于无间隙液体和有间隙液体的粒子系统的混合，并建立了一种实验方法来量化简单流动配置下的混合性能。由于粒子间相互作用引起的偏析和二次现象，粒子系统的混合与流体的混合有显著的不同。即使混合在化学、石油、采矿和制药过程中起着重要作用，也没有发展出具有更大范围普遍性的可靠理论。该方法为发展基于混沌的理论提供了良好的背景，并提供了一种简单的模型校准和测试装置。通过引入各种干扰来加强颗粒的混合，预计会有几项技术改进。该研究项目将侧重于单流体混合和颗粒混合的区别，以及从所提出的装置上的实验可以得到的一般方面。混沌理论应用于颗粒混合的可行性是本项目的主要目标。
