摘要：
An experimental study was conducted to measure the rates of mass transfer from a water drop, suspended from a quartz capillary in a stream of a hot air flowing upward in a vertical wind tunnel. Measurements were made for bulk temperature T(infinity) = 314-449 K, drop temperature T0 = 287-315 K, free stream velocity U(infinity) = 0.5-1.7 m s-1, drop diameter d = 0.7-2.3 mm, dimensionless driving force B = 0.007-0.068, Re = 30-180 and Sc = 0.62. The data were compared with results of previous works. It was found that existing correlations proposed for higher mass transfer conditions do not improve experimental data interpretation
