1. 1. Determination of aerodynamic damping at high reduced frequencies

   Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

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

   Sammanfattning : 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. LÄS MER

3. 2. Akustisk trapping i system med glaskapillär - Systemoptimering och sambandet mellan resonans och trappingkraft

   Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

   Författare :Jacob Wahlström; [2011]
   Nyckelord :Technology and Engineering;

   Sammanfattning : An engineer always strive to help in the continuous exploration of the unknown. By doing so we go further out in space and further down in scale. This is the case with microfluidics which in the last years have gotten a lot of attention. LÄS MER
