A plenum chamber is a pressurised housing containing a fluid (typically air) at positive pressure. One function of the plenum is to equalise pressure for more even distribution, because of irregular supply or demand. Typically a plenum is relatively large in volume and thus has relatively low velocity (compared to other components of a system). In a wind tunnels, rockets, and many flow applications - the plenum is a chamber upstream on the fluid flow where the fluid initially resides (approximately at rest). A plenum chamber can also work as an acoustic silencer device.
