Περίληψη | The effects of acoustic waves on the dissolution of dense nonaqueous phase liquids in
water saturated porous media are investigated. Experiments of trichloroethylene (TCE)
ganglia dissolution within a water saturated column, packed with glass beads, are
conducted. Acoustic waves with pressure amplitudes ranging from 0 to 1625 Pa and
frequencies ranging from 0 to 285 Hz are employed to the interstitial fluid at the inlet of
the packed column. Effluent dissolved TCE concentrations are observed to increase up to
120% in the presence of acoustic pressure waves compared to the case where TCE
dissolution without acoustic waves is monitored. The observed effluent dissolved TCE
concentration increase is attributed to enhanced mass flux at the TCE-water interface,
caused by acoustic waves. Highest dissolution rates occur at discrete frequencies suggesting
resonance effects or the presence of standing waves. Although acoustic waves
enhance TCE dissolution, they dissipate almost exponentially with distance from the
acoustic source | en |
