Controlling Factors of Immiscible Fluid Flow in Porous Media

点击翻译按钮获取中文摘要

Research is conducted on characterization of the manner by which substances, which are only slightly soluble in or miscible with water, move through soil and contaminate groundwater. Sources of these potential contaminants include land fills, hazardous waste disposal sites, and leaking underground storage tanks for petroleum products. A theoretical analysis of the ways by which a fluid is displaced by another from the pore space it occupies is conducted. A mathematical model describing this process is developed, and laboratory experimentation is performed to verify the model-predicted behavior of these fluids.
