A Fluid–Structure Interaction Tool Using a Van der Pol-Based Reduced-Order Model for Buffet and Nonsynchronous Vibrations

Richard Hollenbach, Robert Kielb, Kenneth Hall
Journal: Journal of Turbomachinery
Publisher: ASME
Article Type: Research Papers
J. Turbomach. January 2023, 145(1): 011009.
Paper No: TURBO-22-1189
https://doi.org/10.1115/1.4055447
Published Online: October 7, 2022
...Richard Hollenbach; Robert Kielb; Kenneth Hall This paper builds upon a two-degree-of-freedom Van der Pol oscillator-based reduced-order model for studying the mechanisms around nonsynchronous vibrations (NSV) in turbomachinery. One degree tracks the fluid motion utilizing a combination...

Extending a Van Der Pol-Based Reduced-Order Model for Fluid–Structure Interaction Applied to Non-Synchronous Vibrations in Turbomachinery

Richard Hollenbach, Robert Kielb, Kenneth Hall
Journal: Journal of Turbomachinery
Publisher: ASME
Article Type: Research Papers
J. Turbomach. March 2022, 144(3): 031006.
Paper No: TURBO-21-1165

Published Online: October 4, 2021
...Richard Hollenbach; Robert Kielb; Kenneth Hall This paper expands upon a multi-degree-of-freedom, Van der Pol oscillator used to model buffet and nonsynchronous vibrations (NSV) in turbines. Two degrees-of-freedom are used, a fluid tracking variable incorporating a Van der Pol oscillator...
