Identification of the Aeromechanical Parameters of a Compressor Rotor from Blade Tip Timing Data
Conference Journal of Turbomachinery · July 1, 2024 This article presents a maximum likelihood approach to identifying the mistuning, aerodynamic forcing functions, and aerodynamic influence coefficients of compressor rotor blades from noisy experimental measurements of blade deflection. The maximum likelih ... Full text CiteA Fluid-Structure Interaction Tool Using a Van der Pol-Based Reduced-Order Model for Buffet and Nonsynchronous Vibrations
Journal Article Journal of Turbomachinery · January 1, 2023 This paper builds upon a two-degree-of-freedom Van der Pol oscillator-based reducedorder model for studying the mechanisms around nonsynchronous vibrations (NSV) in turbomachinery. One degree tracks the fluid motion utilizing a combination of a traditional ...

Journal Article Journal of Turbomachinery · March 1, 2022 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 and a classic ... Full text CiteRecent Grants
