Plug Flow is a flow in which there are large bubbles flowing near the top of the tube; semi-slug flow is a flow where very large waves are present on the stratified layer; and Slug Flow is a flow where these waves touch the top of the tube and form a liquid slug which passes rapidly along the channel.
