Content Summary | Correlations describing the rate of interface mass transfer from singlecomponent
nonaqueous phase liquid (NAPL) pools in saturated subsurface formations are
developed. A three-dimensional contaminant transport model is employed to obtain
overall mass transfer coefficients computed from concentration gradients at the NAPLwater
interface. The model assumes that the porous medium is homogeneous, the
interstitial fluid velocity is steady, and the dissolved solute may sorb under local
equilibrium conditions. Furthermore, it is assumed that the dissolved concentration along
the NAPL-water interface is equal to the solubility concentration. Power law correlations
relate the overall Sherwood number to the appropriate overall Peclet numbers. Both
rectangular and elliptic/circular source geometries are considered. The proposed
relationships are fitted to numerically determined mass transfer coefficients, and the
correlation coefficients are determined by nonlinear least squares regression. Good
agreement between predicted and available experimentally determined overall mass
transfer coefficients is observed | en |
