Abstract: Measured leakage flow and rotordynamic coefficients for six, circumferentially-grooved, liquid seals are compared to predictions based on Nordmann et al.’s (1986) grooved seal model. The grooved ...

Abstract: Test results, consisting of leakage data, friction factors, and rotordynamic force coefficients, are presented for seven annular seals using smooth rotors and helically-grooved stators. All seals ...

Abstract: Test results are presented for round-hole-pattern damper seals at Reynolds numbers on the order of 90,000 to 250,000. The seals have roughened stators; Cr /R = 0.0075 and L /D = 1/2. The ...
