RISRotordynamic Behavior of Leaf Seals: Measurement of Frequency-Dependent Force Coefficients for Varying Inlet Parameters
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: While brush seals can be found in various applications for turbomachines today, leaf seals are a further development in compliant seal technology and have a lower level of maturity. Among the purported advantages are greater ...
Impact Analysis of Pocket Damper Seal Geometry Variations on Leakage Performance and Rotordynamic Force Coefficients Using Computational Fluid Dynamics
Publisher: The American Society of Mechanical Engineers (ASME)
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 ...
Analysis of Leaf Seal Leakage Performance Under the Influence of Manufacturing Variations Using Experiment and Computational Fluid Dynamics
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, test data are combined with results from two different computational fluid dynamics (CFD) models to investigate the leakage performance of leaf seals. Experimental data are gathered for centric rotor position ...
