✦ Synopsis

The evaporation of a water drop into a ternary gaseous mixture only describe the results of observations (8,9). of air, steam, and naphthalene vapor was investigated. The experi-We investigated the evaporation of a water drop in ternary mental results were compared with a theoretical prediction based gaseous mixture containing air, steam, and traces of naphthaon a numerical solution of coupled boundary layer equations for lene (10). The work was a continuation of the previous study heat and mass transfer from a drop moving in ternary gas. In the on mass transfer from evaporating drops (11) that was used experiments the naphthalene vapor condensed on the water drop for verification of a new mass transfer correlation (12). The as a supercooled liquid even at temperatures far below the melting aim of this study was to determine experimentally the conpoint of naphthalene. The condensation on drop surface is disdensation-evaporation behavior of the system (boundary cussed in terms of classical theory of heterogeneous nucleation on smooth surfaces. ᭧ 1997 Academic Press layer condensation, formation of solid or liquid deposits on Key Words: evaporation of drop; surface condensation; heterogethe drop) and to prove the applicability of the model of the neous nucleation.
