【 摘 要 】

References(14)Cited-By(1)Experiments on the condensation of binary vapor mixtures of methanol-steam and acetone-ethanol systems on a short horizontal tube were made for a wide range of vapor flow rates and concentrations. The observed vapor phase sensible heat and diffusion fluxes showed good agreement with the authors’ previous numerical correlation for heat and mass transfer on a cylinder with high mass flux effect.The effect of vapor flow rates and cooling water temperatures on partial condensation, where the concentration of condensate is lower than that of vapor free stream, was discussed. A new method for predicting the concentrations of condensate of binary vapor mixtures on a short horizontal tube was proposed, and compared with the experimental data under total and partial condensation.
