This paper provides a new analytical model of airflow to inlet wells in soil vapor extraction systems. It is based on a recent analytical solution of airflow to a single vapor extraction well by Bahr and Joss (1995), which updated the previous model of Baehr and Hult (1991). Baehr and Joss (1995) treated the air leakage through the surface as an air flux boundary condition, whereas Baehr and Hult (1991) approximated the leakage as a distributed source imposed in the governing airflow equation. The new analytical model shows significant improvement on air‐flow assessment over the previous model by Ge and Liao (1996), which could underestimate the efficiency of airflow to inlet wells by as much as 27% in a typical vapor extraction system.
