Morphology of Colloidal Deposits in Porous Media

CTS-9634213马克·韦斯纳·莱斯大学摘要该项目是研究颗粒大小和流体流动对胶体沉积物形态的影响。将进行实验，以评估颗粒在颗粒多孔介质上的附着，并使用显微镜直接观察特定的处置。由光散射、沉积和图像分析确定的质量分布的幂函数关系将表征矿床的形态。将发展理论，根据物理化学特征预测矿床形态的趋势。将蒙特卡罗模拟结果与理论结果进行比较。这一结果可能有助于更好地理解液-固分离在各种制造和环境应用中的应用。

CTS - 9634213 Mark Weisner Rice University ABSTRACT This Project is an investigation of the effects of particle size and fluid flow on the morphology of colloidal deposits. Experiments will be performed to evaluate particle attachment on granular porous media and directly observe particular disposition using microscopy. The deposit morphology will be characterized by power-law relationships of mass distribution as determined by light scattering, sedimentation and image analysis. Theory will be developed to predict trends in deposit morphology based on physical-chemical characteristics. Monte Carlo simulation results will be compared to theory. The results may lead to an improved understanding of liquid-solid separations used in various manufacturing and environmental applications.
