Two Phase Flow Demonstrator

Two Phase Flow Demonstrator 

Description of Two Phase Flow Demonstrator

The Two Phase Flow Demonstrator apparatus is a small scale flow loop that can demonstrate Two Phase Flow phenomena in pipes at a variety of liquid and gas flow rates. Two Phase Flow occurs when a gas is flowing in a confined space with a liquid. The flow profile and geometry in this instance varies widely as a function of the liquid and gas material properties as well as the flow rates through the pipeline. Certain flow regimes can be destructive to facility piping, and should be avoided where possible. The destructive effects of these flow regimes can be managed through the use of various piping geometries. It is important that the process operator understand the basics of Two Phase Flow Demonstrator in pipelines, especially as it pertains to the formation of the destructive slug flow regime.

Two Phase Flow Demonstrator uses air and water to create different flow regimes in the process piping. Air is supplied to the system by a low pressure blower, and water is supplied through a centrifugal pump. The air and water flow rates are continuously variable over a wide range of flow rates. This allows the operator to observe a wide range of two-phase flow regimes using this demonstrator. The Two Phase Flow Demonstrator is mounted on a movable cart for ease of movement and storage.
