dc.description.abstractLeakage resistance measurements were conducted on stepped labyrinth seals using a 4-1 scale, two-dimensional, non-rotating test apparatus, with water as the working fluid. By sequentially varying the dimensions of a labyrinth sea], changes in geometrical design parameters were evaluated for their effects on the leakage resistance characteristics of a typical labyrinth seal. Specific design parameters evaluated were labyrinth seal clearance gap, labyrinth seal step height, and stator annular groove width. All three parameters were tested for a variety of dimensions and flow rates. Each parameter evaluated produced a significant effect on leakage resistance, both acting alone and in conjunction with the other design variables. Non-dimensionalized plots were prepared using the results of the experimental process to show the effects of geometry changes on the performance of labyrinth seals. Beneficial results were gained by the judicious positioning of an annular groove on the stator portion of the labyrinth seal and by increasing the value of the step height. Reduction of seal clearance was confirmed as a means of increasing labyrinth seal leakage resistance.en_US
