Abstract. The problem of joint gas outflow with near-wall liquid film from an axisymmetric cylindrical channel into vacuum is studied experimentally. It is shown that liquid film at the exit edge of the channel not only disintegrates into droplets, but also emerges on the external surface of the channel and starts moving in the opposite direction to the gravitational force. The phenomenon revealed is strongly dependent on physical properties of liquid and pressure in the surrounding space. Temperature of a film formed on the external surface of the channel is measured. It is shown that due to evaporation in vacuum liquid film is cooled to temperature at which the saturated vapor pressure is close to pressure in vacuum chamber.
