Equipment Grant: Digital Image Processing and Analysis Equipment for Videomicroscopy Studies

数字图像处理和分析设备是对油-水-表面活性剂体系中动态界面现象进行视频显微镜研究的先决条件；该项目将获得一个数字图像处理和分析系统，以提高图像质量并从记录的图像中提取定量信息。表面活性剂溶液与非极性和弱极性油接触时的动态行为将使用一种新的垂直池技术进行研究，该技术可以清楚地看到中间相的生长和自发乳化。这些研究与理解清净性的机理以及在提高采油过程中发生的各种非平衡行为有关。扩散路径理论将被扩展并用于解释结果。此外，还将致力于研究乳状液的动态行为，特别是乳状液的破碎和转化过程。

Digital image processing and analysis equipment is a prerequisite for conductingvideomicroscopy studies of dynamic interfacial phenomena in oil-water- surfactant systems; this project will acquire a digital image processing and analysis system for improving image quality and extracting quantitative information from the recorded images. Dynamic behavior accompanying contact of surfactant solutions with nonpolar and slightly polar oils will be investigated using a novel vertical cell technique which allows a clear view of the growth ofintermediate phases and of spontaneous emulsification. These studies arepertinent to understanding the mechanism of detergency and to various types of nonequilibrium behavior which occur during enhanced oil recovery processes. Diffusion path theory will be extended and used to interpret the results. A major effort will also be directed toward investigating the dynamic behavior of emulsions, especially emulsion breaking and inversion processes.
