The influence of wettability on NAPL dissolution fingering

Interphase mass transfer between fluids in subsurface formations: A review

“…Imhoff and Miller [116] reported that the non-uniform distribution of residual NAPL leading to variation in flow velocity between pores is the primary reason for this phenomenon. On the other hand it has been also shown that such fingers are limited in length due to transverse dispersion [117][118][119].…”

“…The authors also showed that within high fraction of NAPL-wet media (>75%), grain size is not influential on the interphase mass transfer rate, whereas for low fraction NAPL-wet media (10%), decreasing the median grain size leads to lower mass transfer rates. In addition Seyedabbasi et al [119] showed that the dissolution fingering reduces when the medium becomes more NAPL-wet.…”

“…The configuration of fluids on the solid surface is affected by aqueous chemistry, solid phase mineralogy, organic matter distribution, surface roughness and charge, and contaminant aging [119]. Generally aquifer solids are accepted as water wet however non-water wetting or partially NAPL-wetting media can also be found [186].…”

“…Seyedabbasi et al [119] improved the model of [260] to account for the influence of wettability of the medium (i.e., different flow configurations) by incorporating: i) the Modified Mualem's approach [190] which relates the relative permeability to the wettability of the media and ii) the interphase mass transfer formulation developed by Bradford et al [104].…”

Theoretical analyses of nonaqueous phase liquid dissolution‐induced instability in two‐dimensional fluid‐saturated porous media

“…The transport of nonaqueous phase liquids (NAPLs) in contaminated subsurface is an important problem in geoenvironmental engineering [1][2][3][4][5][6][7][8][9][10]. The NAPL, which is usually trapped at the residual saturation in the pore space of a fluid-saturated porous medium, can become long-term sources of groundwater contamination as a result of its low solubility.…”
