Carbon Seal

A carbon seal is used to prevent the gas from leaking through the space between a rotating and a static device and thus reducing the efficiency (Figure 89).

Figure 89: Geometry of a carbon seal

The formula governing the flow through a carbon seal has been derived in [72]. A carbon seal is described by the following parameters (to be specified in that order on the line beneath the *FLUID SECTION,TYPE=CARBON SEAL card):

Please look at the figure for the meaning of these parameters.
