Numerical Simulation of Air Flow during Air Sparging Remediation

Abstract:

A 2D numerical model is used to modeling the movement of air during air sparging process for groundwater remediation. The zone of influence (ZOI) and the water saturation distribution can be obtained from the calculations. The results agree well with the centrifuge test data, indicating the two-phase flow model is reasonable for numerical simulation of air sparging process. It was also shown that air compressibility has a significant influence on the extent of ZOI.
