  3. 2. Determination of aerodynamic damping at high reduced frequencies

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Minghao Pan; [2017]
    Keywords : Aerodynamic damping; reduced frequency; forced response; acoustic mode; acoustic resonance; Aerodynamisk dämpning; reducerad frekvens; aerodynamiskt påtvingade vibrationer; akustiskt svängningsform; akustisk resonans;

    Abstract : Forced response which is blade vibration due to an external excitation can lead to blade failure. The estimation of the level of vibration is dependent on the determination of aerodynamic damping. This thesisinvestigates the determination of aerodynamic damping at high reduced frequencies in turbomachines. READ MORE
