RISNumerical Study of Low Engine Order Excitations Due to Manufacturing Variability Part II: An Efficient Approach for Stochastic Studies
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In turbomachinery rows, the geometric variability between the airfoils induces nonuniformity in the flow, which directly translates into low engine order (LEO) excitation and vibration in the adjacent rows. Direct simulations ...
Numerical Study of Low Engine Order Excitations Due to Manufacturing Variability Part I: Characterization of the Geometric Scatter and Its Effect on Forced Response
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The geometric scatter in the surfaces of blades and vanes due to manufacturing variability has an impact on the dynamics (structural mistuning) that has been widely studied, but also on the aerodynamics. This geometric ...
Experimental Research Into Aeroelastic Phenomena in Turbine Rotor Blades Inside ARIAS EU Project
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper describes an aeroelastic experimental campaign on a low-pressure turbine-bladed rotor in a rotating wind tunnel that took place as a part of the Advanced Research Into Aeromechanical Solutions (ARIAS) EU project. ...
