Titel:
CFD-predicted rotordynamic coefficients for a 20-teeth-on-stator labyrinth seal at high supply pressure conditions 
Abstract:
A twenty-teeth-on-stator labyrinth seal with a tooth radial clearance of 0.1 mm is modeled using a CFD method to predict leakage performance, as well as stiffness and damping coefficients. The calculations are performed at a supply pressure of 70 bar for three shaft rotational speeds (10200 rpm, 15200 rpm, and 20200 rpm), three preswirl ratios (low, medium, and high), and three pressure ratios (0.1, 0.35, and 0.5). The predicted performance of the seal is compared to experimental data obtained b...    »
