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.

CTS -9634213 Mark Weisner Rice University摘要该项目是对粒度和流体流动对胶体沉积物形态的影响的研究。 将进行实验以评估颗粒多孔培养基上的颗粒附着，并直接使用显微镜观察特定的处置。 沉积的形态将以质量分布的幂律关系为特征，如光散射，沉积和图像分析所确定。理论将基于物理化学特征来预测沉积形态的趋势。 蒙特卡洛模拟结果将与理论进行比较。 结果可能会导致人们对各种制造和环境应用中使用的液体固体分离的了解得以提高。
