Advective Transport from Defects in Porous Geological Media

摘要

This paper presents the problem of advective transport of a chemical from the pressurized boundary of a three-dimensional spheroidal cavity region. The results are presented in exact closed form; the solutions to problems dealing with advective transport from a flat crack or an elongated borehole can be obtained as limiting cases of the spheroidal shape. The solution presented also accounts for attenuation of the migration chemical and can be extended to include transient decay of both the pressure in the cavity region and the chemical concentration at the boundary.
