Werth, Charles J. Chomsurin, Cheema 2015-09-25T21:03:32Z 2015-09-25T21:03:32Z 10000-01-01 2003 2003 NAPL volumes and surface areas were used as input parameters to calculate mass transfer coefficients for dissolution in all micromodel experiments. Mass transfer coefficients for the homogeneous and heterogeneous micromodels initially increased with water velocity but then leveled off to a relatively constant value. Also, these mass transfer coefficients varied with pore and NAPL blob geometry. Specifically, the mass transfer coefficient decreased with increasing blob size because larger blobs had more NAPL-water interfacial area not adjacent to flowing water, and with decreasing pore throat width to pore throat depth because NAPL interfaces in deeper more narrow pores were adjacent to more stagnant water. For each of these cases the mass transfer coefficient decreased because the average diffusion length adjacent to NAPL blobs increased. Made available in DSpace on 2015-09-25T21:03:32Z (GMT).
