Experimental data are presented on the pressure drop, mean liquid film thickness, state of gas-liquid interface, droplet entrainment and its momentum, and heat transfer coefficient for downward annular and annular-mist two phase (two-component) flow in a vertical tube. From these data, the relation between the state of interface and the friction factor of gas stream in the core, and the relation between the liquid film flow rate and the mean film thickness are discussed. The characteristics of the mean film thickness with respect to the film Reynolds number are revealed comparing with the analytical predictions for laminar and turbulent films. On the basis of the experimental results of heat transfer coefficient, a correlation of the laminar sublayer thickness of liquid film is also presented for the mean film thickness.
