9.4 Periodic Flows

Periodic flow occurs when the physical geometry of interest and the expected pattern of the flow/thermal solution have a periodically repeating nature. Two types of periodic flow can be modeled in FLUENT. In the first type, no pressure drop occurs across the periodic planes. In the second type, a pressure drop occurs across translationally periodic boundaries, resulting in "fully-developed'' or "streamwise-periodic'' flow.

This section discusses streamwise-periodic flow. A description of no-pressure-drop periodic flow is provided in Section  7.15, and a description of streamwise-periodic heat transfer is provided in Section  13.4.

Information about streamwise-periodic flow is presented in the following sections:
