要約

Direct-contact evaporation of volatile-liquid lenses due to the heat supply from a liquid substrate has been studied both experimentally and numerically. Experiments were performed with single n-pentane lenses placed on the surface of an otherwise quiescent pool of water which was in contact with common vapors of the two liquids. A laser-shadowgraphy technique was used to detect any possible convection induced in the water substrate, due to the local cooling caused by each evaporating lens. A numerical analysis employing an explicit finite-difference scheme was also made to simulate the convection and to evaluate its effect on the heat transfer.
