For horizontal pneumatic transport, various flow patterns are identified which depend on several factors such as flow velocity and particle loading. The velocity at which particles begin to settle out is called the saltation velocity. Further reduction in velocity leads to slug flow where there are alternate regions where particles fill the pipe and where they are in suspension. The flow behaves like slug flow of the gas-liquid flow regimes.
