General computer program for calculating axisymmetric temperature field applied to gas turbine face seal thermal deformation
Rotating shaft seals used in space power systems have spiral grooves in one or both of the opposing seal faces. These grooves induce a pumping action which displaces the intervening fluid radially inward toward the shaft and counters the centrifugal forces which tend to displace the fluid outward.
