Jan 13, 2010· David Mills, PhD Two basic modes of flow are possible for materials in pipelines: dilute phase or suspension flow, and dense phase or nonsuspension flow. For densephase conveying there are two possibilities, dependent upon material properties. One is sliding bed flow, for materials that have good air retention, and the other is plug flow, for materials with good permeability.
