Evaporation Suppression

An experimental investigation has been conducted to quantify the extent by which monolayers of fatty alcohols can reduce evaporation from a deep stationary water pool within a controlled environment. Octadecanol (stearyl alcohol), C17H35–CH2–OH, was chosen as the surface film and ethanol was selected to be the spreading agent. Evaporation suppression of 60 percent was achieved at a water temperature of 25°C with an air temperature of 20°C and a relative humidity of 70 percent. The experimental techniques and data have been validated by comparing the measured evaporation rates for film-free water with earlier data published by other investigators. Data for the evaporation rates of water covered by octadecanol films were correlated as a function of vapor concentration differences between the water surface and air.

Set Up

In an extensive experimental investigation (Christodoulou, 1985) the performance of a disk skimmer rotating in the vertical plane and partially immersed in a liquid has been studied. The aim of the study was to examine the physical and hydrodynamic parameters governing the oil collection rate of the disk when used as one element of a rotating disk skimmer, a device commonly employed to recover oil and similar immiscible liquids from a water surface. This paper presents a theoretical solution for the flow field set up by the disk which has led to an improved understanding of the hydrodynamics of the disk drag-out problem at low to moderate speeds. Experimental data are presented and compared with the theoretical solutions: discrepancies are then explained in terms of departures from the original assumptions.
