Research on dropwise condensation for binary mixed vapor

摘要：

　　An experiment for Marangoni condensation of ethanol-water mixtures was carried out and the departing radius and drop size distribution on vertical surface was presented.An amended formula was obtained after considering the effect of ethanol mass concentration, vapor velocity and condensing temperature difference based on Le Fevres formula concerning departing radius of pure water, The calculations were in good agreement with experimental result, had a maximum error less than 23%.Owing to the significant effect on drop size contribution, vapor velocity was introduced into Roses formula, and the correctional result compared well with the experimental data.
