Hydrodynamics of Fluidization: Structure and Turbulence

摘要CTS-0086250 D。这是NSF在过去六年中支持的一项研究的继续。 其目的是获得一个很好的定量了解流动颗粒悬浮液（流化），包括它的一些主要特性（雷诺应力，颗粒温度，气泡和颗粒尺寸）。 挑战在于为每种相和颗粒类型的传统守恒方程添加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，有可能生成一个预测理论，对流动进行更准确和详细的描述。 提出了一些实验（七），以建立必要的现象学常数为不同的多相混合物：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.
