Experiments　were　carried　out　to　investigate　condensation　of　ethanol-water　vapor　mixtures　on　a　vertical　mini-tube　with　outer　diameter　of　1.032mm.　The　length,　inter　diameter　of　the　tube　was　110mm,　0.727mm,　respectively.　The　tests　were　performed　at　a　wide　range　of　ethanol　concentrations　((Cv=0%,　1%,　2%,　5%)　and　varied　velocity　of　vapor　((Uv=2m/s,　4m/s,　6m/s)　and　pressure　((Pv=31.2kPa,　47.4kPa,　84.5kPa).　With　the　change　of　the　vapor-to-surface　temperature　difference,　the　heat　transfer　coefficients　revealed　nonlinear　characteristics　with　the　peak　values　under　all　ethanol　mass　fractions　of　vapor.　The　heat　transfer　coefficients　decreased　with　increasing　ethanol　mass　fraction　of　vapor.
