Acoustically Enhanced Remediation of Aquifers Contaminated with Nonaqueous Phase Liquids (TSE03-P)

0329398 克里希科普洛斯 本提案的具体目的是实验研究对饱和多孔介质中的残余相NAPLs施加声波以增强溶解并引起动员的可行性。我们的建议旨在采用孔隙网络和单层珠实验，涉及剩余相致密NAPL（DNAPL）的饱和度和神经节，除了声波恒定的背景水流。为这项工作进行网络和单层珠实验的原因有三个。首先，这两个实验允许直接观察和测量DNAPL动员由于声波。第二，直接观察/测量DNAPL水界面面积将允许准确确定传质系数，这在柱实验中无法确定，有和没有添加声波。 第三，也是最后一点，由于采用了规则的孔几何形状，使用孔网络和单层珠实验将允许流体流动的精确描述

0329398 Chrysikopoulos The specific aim of this proposal is to experimentally investigate the feasibility of applying acoustic waves toward residual phase NAPLs in saturated porous media to enhance dissolution and cause mobilization. Our proposal seeks to employ pore network and monolayer bead experiments involving residual phase dense NAPL (DNAPL) saturations and ganglia with the addition of acoustic waves to constant background water flow. The reasons for performing network and monolayer bead experiments for this work are three fold. First, both experiments allow direct observation and measurement of DNAPL mobilization due to acoustic waves. Second, direct observation/measurement of the DNAPL water interfacial areas will allow exact determination of mass transfer coefficients, that cannot be determined in column experiments, with and without the addition of acoustic waves. Third and finally, use of pore network and monolayer bead experiments will allow a precise description of fluid flow due to the regular pore geometries employed
