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 57).
The formula governing the flow through a carbon seal has been derived in [51]. 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):
- D: largest diameter of the gap
- s: size of the gap between rotor and carbon ring
- L: length of the carbon seal
Please look at the figure for the meaning of these parameters.
