Περίληψη
A three-dimensional numerical flow and
contaminant transport model is developed to investigate
the effect of variable hydraulic conductivity on
average mass transfer coefficients associated with the
dissolution of dense nonaqueous phase liquid
(DNAPL) pools in heterogeneous, water-saturated
subsurface formations. Randomly generated, threedimensional
hydraulic conductivity fields are used to
represent a heterogeneous confined aquifer. Model
simulations indicate that the average mass transfer
coefficient is inversely proportional to the variance of
the log-transformed hydraulic conductivity. A power
law correlation relating the Sherwood number to the
variance of the log-transformed hydraulic conductivity
and appropriate Peclet numbers is developed.
A reasonable fit between predicted and numerically
determined mass transfer coefficients is observed
