Two Phase Flow Demonstrator (Enhanced Version)

The Two-Phase Flow demonstration 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 (such as a pipe) with a liquid. The flow profile and geometry in this instance vary 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. The process operator must understand the basics of two-phase flow in pipelines, especially as it pertains to the formation of the destructive slug flow regime.

The Two-Phase Flow Demonstrator uses air as the gas phase and water as the liquid phase to create different flow regimes in the process piping. Air is supplied to the system by a low-pressure blower and liquid is supplied through a centrifugal pump. The air and liquid 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 demonstrator is mounted on a purpose-built SS frame for ease of

movement and storage.
