Bubbles never attach to the surface of a solid body of good wettability, while bubble attachment is usually observed when the wettability of the surface of a solid body is poor. This phenomenon was used to separate gas and liquid in gas-liquid two-phase flows in a vertical pipe. Air and water ascending in the vertical pipe was satisfactorily separated by using a T-junction. The dispersed gas phase, i.e., bubbles and slugs, passed preferably through the poorly wetted side of the T-junction. The separation efficiency increased with a decrease in the air flow rate.
