AbstractCTS-0086250D. Gidaspow, Illinois Institute of TechnologyThis is the proposed continuation of a research supported by NSF for the last six years. Its objective is to obtain a good quantitative understanding of the flow particle suspensions (fluidization), including some of its main characteristics (Reynolds stresses, granular temperature, bubbles and particle size). The challenge is to add to the traditional conservation equations for each phase and particle type, the phenomenological properties of the mixtures involved (e.g. viscosity). With this information, it was shown early in this research that it is possible to generate a predictive theory with a more accurate and detailed description of the flow. A number of experiments (seven) are proposed to establish the necessary phenomenological constants for different multiphase mixtures: gas-solid, gas-liquid-solids, bubbling beds.

abstractcts - 0086250 d。这是一项由美国国家科学基金会（NSF）在过去六年中支持的研究的拟议延续。其目的是获得对流动颗粒悬浮液（流态化）的良好定量理解，包括其一些主要特征（雷诺应力、颗粒温度、气泡和粒径）。挑战在于为每一种相和粒子类型的传统守恒方程加上所涉及的混合物的现象学性质（例如粘度）。有了这些信息，在这项研究的早期就表明，有可能产生一个更准确、更详细地描述流的预测理论。为了建立不同多相混合物（气-固、气-液-固、鼓泡床）的必要现象学常数，提出了若干实验（7个）。
