Analytical solutions of nonaqueous-phase-liquid dissolution problems associated with radial flow in fluid-saturated porous media.

Highlights: [•] To derive analytical solutions for NAPL dissolution problems with radial flow. [•] Three key factors can affect the propagating speed of an NAPL dissolution front. [•] Three key factors can also affect the location and breakthrough time of an NAPL dissolution front. [•] The Zhao number can be used to represent the overall hydrodynamic characteristic of a NAPL dissolution system. [•] Several key factors can also affect the distribution pattern and evolution of the NAPL dissolution front. [Copyright &y& Elsevier]
