DISTRIBUTION OF LIQUID AND FORMED VAPOUR IN UNHEATED AND HEATED TUBE WITH A HIGH VELOCITY AIR FLOW
摘要
Measurements of mass velocity of water drops (and formed vapour) in unheated (and heated) 20 mm internal diameter tube with air turbulent flow are made. For unheated tube, a mean droplet diameter was measured. During experimental testing the air velocity varied from 70 to 140 m/s, the water flow rate from 3 to 15 g/s, the heat flux reached 380 kW/m2. The results obtained here are analysed and compared with other experimental data. Theoretical models for prediction of roll waves formation, liquid entrainment and equilibrium liquid film flow are proposed.
