Hydrodynamics of Fluidization: Structure and Turbulence

摘要CTS-0086250D。吉达斯波，伊利诺伊理工学院这是过去六年来由美国国家科学基金会资助的一项研究的拟议继续。它的目的是对流动颗粒悬浮(流态化)，包括它的一些主要特征(雷诺应力、颗粒温度、气泡和颗粒尺寸)有一个很好的定量了解。所面临的挑战是在每种相和颗粒类型的传统守恒方程中添加所涉及的混合物的唯象性质(例如粘度)。有了这些信息，在这项研究的早期就表明，有可能产生一个预测理论，对流动进行更准确和详细的描述。提出了一些实验(7)来建立不同多相混合物所需的唯象常数：气-固、气-液-固、鼓泡床。

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.
