Flow problems in air venting and air sparging
Soil Vapor Extraction (SVE) and Air Sparging have been used for site remediation for about ten years, but most of the past designs are based on experiences and numerical models. Understanding toward the physical problems is far from complete, and some simplified assumptions used in those models may …

Influence of Soil Moisture Dynamics on DNAPL Spill Zone Architecture and Its Impact on Mass Removal Mechanisms During Soil Vapor Extraction in Heterogeneous Porous Media
… of DNAPL saturation, water saturation, and soil permeability (i.e., spill zone architecture) determines the pore-scale processes that control soil vapor extraction (SVE). To test this hypothesis, a fully coupled multiphase flow and transport simulator, STOMP was chosen. STOMP was first used …

Computational Tools for Improved Analysis and Assessment of Groundwater Remediation Sites
… zone remedial technique with MNA. Excavation and soil vapor extraction when applied to the front end of a remedial action plan can decrease the amount of time to remediation and while generally more expensive than an MNA-only approach, may accrue long-term economic advantages that would otherwise …
