Slugging of countercurrent stratified air-water flow has been investigated in horizontal and in nearly horizontal channels. The tests were performed in the rectangular channels, 35 mm wide and 3 m long. Three channel depths, 25, 35, and 60 mm, were employed. The onset of slugging in the channel inclined to keep a constant liquid level in the channel was compared with that in the horizontal one. Independent of the channel depth and the channel slope. All the data correlated with the relation between the gas velocities relative to the interfacial wave celerity and local gas channel depth. Comparing with cocurrent flow, the relative gas velocities at slug formation were high. It is presumed to be caused by the difference in the shapes of interfacial waves. The deflection of liquid level in horizontal countercurrent stratified slow was also examined by means of the principle of minimum entropy production.
