This research is a theoretical and experimental study of the detachment of particles from surfaces by flowing liquids. The effects of particle size, particle material, fluid motion, electrical double layers, and liquid - liquid interfaces will be explored. Release rates will be determined from the measured concentration of particles in the liquid flowing past a particle laden surface and/or by microscopic observation of the particle laden surface. The kinetics of particle removal from surfaces is poorly understood, yet is of very great importance to surface cleaning, filtration efficiency, contamination transport, oil field permeability control, and other applications.

本研究是一个理论和实验研究， 通过流动的液体使颗粒从表面脱离。 的影响 颗粒大小，颗粒材料，流体运动，电双 层和液-液界面将被探索。 释放 速率将根据测量的颗粒浓度确定 在流过载有颗粒的表面的液体中和/或通过 载有颗粒的表面的显微镜观察。 从表面去除颗粒的动力学知之甚少， 但对于表面清洁、过滤 效率，污染物迁移，油田渗透率控制， 和其他应用。
