Title:
Impact analysis of pocket damper seal geometry variations on leakage performance and rotordynamic force coefficients using CFD 
Pages contribution:
GT2018-76864 
Abstract:
In this paper, different notch and partition wall arrangements of a fully partitioned pocket damper seal (FPDS) are investigated using Computational Fluid Dynamics (CFD). The CFD model is derived for a baseline FPDS design reflecting the full sealing configuration with a structured mesh. Steady-state simulations are performed for eccentric rotor position and different operational parameters. The results are validated using experimental cavity pressure measurements. In transient c...    »
