Influence of Geometric Tooth Shape Parameters of Labyrinth Seals on the Flow Law and the Algorithm for Designing Straight Grate Teeth

Investigation of Leakage and Heat Transfer Properties of the Labyrinth Seal on Various Rotation Speed and Geometric Parameters

“…When the width-depth ratio was greater than the critical value, the sealing performance of the grooved labyrinth seals was about 15 percentage points higher than that of the smooth labyrinth seals. Zhang et al [19] studied the influence of the change of labyrinth seal shape parameters on sealing performance, and proposed the criterion relation formula for labyrinth seal design. Du et al [20] obtained the correlation between the labyrinth shape parameters and the flow coefficient through an orthogonal experimental study, and ranked the correlation influence degree.…”
