Abstract

On the basis of mathematical modeling, the values of velocities above the liquid surface in the experimental vessel are obtained to ensure the condition of droplet detachment and entrainment. The program of physical experiments on the entrainment of liquid droplets from experimental vessel is developed. Physical modeling of liquid droplets entrainment from experimental vessel is carried out, which showed that the separated mass of liquid significantly depends on the parameters of the gas flow at the inlet to experimental vessel (temperature, flow velocity). At the temperature of the inlet gas flow equal to 20 °C the percentage of separation ts 62 %, at 30 ºC — 69 %, at 35 ºC — 70 %, at 40 ºC — 78 %.
