The Effect of Surface Films on Concentration Fluctuations Close to a Gas/Liquid Interface

Document Type: Proceeding Paper

Part of: Water Quality Issues at Fossil Fuel Plants

Abstract:

Modeling of gas/liquid mass transport requires knowledge concerning the behavior of near-surface concentration fluctuations at clean and film-covered gas/liquid interfaces. Previous measurements of concentration fluctuations were performed with invasive sampling techniques or for water surfaces of unknown cleanliness. Here, concentration fluctuation depths were calculated from noninvasive laser-induced fluorescence measurements of surface fluorescence fluctuations for carefully cleaned and film-covered water surfaces for a range of turbulence intensities. Comparison of the film-covered water surface concentration fluctuation depths to previous measurements of concentration fluctuations shows that the calculational procedure provides accurate estimates of fluctuation depths.
