【Abstract】 According to the specialty of immiscible mixture vapor condensation on the wall in a vertical tube, a mathematical model is developed to forecast the velocity limit of immiscible mixture vapor condensed on the wall in a vertical tube. The experiments have been conducted with the oil-water mixture vapors condensed on the wall in a brass tube and a glass tube respectively. The comparison between the present model-predicted data and experimental data obtained in this paper indicates that the mathematical model is suitable for the forecast of velocity limit of the immiscible mixture vapor condensed on the wall in a vertical tube.更多还原
