Progress in air sparging for Groundwater Remediation Technique
Water Resources Protection, 2010Co-Authors: Yang Ming-xingAbstract:A state-of-art of study on air sparging(AS) for in situ Groundwater Remediation is summarized based on analysis of the air flow pattern and mass transfer.The existing problems in the current study are presented,including interactions among Groundwater flow,soil media,and air flow patterns,the rationale of the pulsed flow mode,and the conjunction with soil vapor extraction and biodegradation in AS.The prospects of this Technique are discussed in terms of technologic improvement and engineering of the optimal design and mechanism study,which can provide guidance for further study and applications.

study of flow transitions during air sparging using the geotechnical centrifuge
Journal of Environmental Engineering, 2015Co-Authors: Liming Hu, Jay N. Meegoda, Hengzhen Li, Jian Ting DuAbstract:AbstractAir sparging (AS) is an in-situ Groundwater Remediation Technique for volatile organic compounds (VOCs) in contaminated sites. Knowledge of effect of the injected air on air flow patterns and extent of the zone known as zone of influence (ZOI) is crucial for design of in situ air sparging. The two main objectives of this research are to study transition of air flow patterns and characteristics of ZOI under different air injection pressures during centrifugal tests and to find the scaling factors for centrifugal tests under different gravitational levels (N times gravitational force). In this research, the modeling of models test was first performed to validate centrifugal Technique for simulating air sparging. Then, a set of two-dimensional (2D) centrifugal modeling tests were performed under various gravitational levels to study the transition of air flow patterns and characteristics of ZOI during air sparging. The centrifugal model tests showed that the observed 2D ZOI was truncated-cone under v...
