Measurement versus predictions of rotordynamic coefficients and leakage rates for a hole-pattern gas seal with negative preswirl /

This thesis presents the results of high supply (up to 84 bar) pressure testing of hole-pattern annular gas seals performed at the Texas A & M Turbomachinery Laboratory in College Station, TX. The test variables were chosen to determine the influence of pressure ratio, rotor speed, and negative...
