RISNonlinear Flutter Analysis of Labyrinth Seals
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A simple nonlinear model to describe labyrinth seal flutter has been developed to assess the aeromechanic stability of straight-through labyrinth seals subjected to large gap variations. The model solves the one-dimensional ...
Effective Clearance and Differential Gapping Impact on Seal Flutter Modeling and Validation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents an update of the model derived by Corral and Vega (2018, “Conceptual Flutter Analysis of Labyrinth Seal Using Analytical Models. Part I—Theoretical Support,” ASME J. Turbomach., 140(12), p. 121006) for ...
Higher Order Conceptual Model for Labyrinth Seal Flutter
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A simple nondimensional model to describe the flutter onset of two-fin straight labyrinth seals (Corral, R., and Vega, A., 2018, “Conceptual Flutter Analysis of Labyrinth Seals Using Analytical Models. Part I: Theoretical ...
Conceptual Flutter Analysis of Stepped Labyrinth Seals
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A simple nondimensional model to describe the flutter onset of two-fin straight labyrinth seals (Corral and Vega, 2018, “Conceptual Flutter Analysis of Labyrinth Seals Using Analytical Models—Part I: Theoretical Background,” ...
A Test Facility for the Experimental Investigation of Labyrinth Seal Flutter and Early-Stage Validation of Prediction Techniques
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. The ARIAS project involved the development of novel seal flutter prediction approaches and their full validation against data generated with a state-of-the-art test facility to improve understanding of this ...
