  1. 6. Research and Testing of an Electromechanical solution for Vibration Assisted Drilling of Aerospace Materials

    University essay from Uppsala universitet/Solcellsteknik

    Author : Jonathan Nordenholm; [2020]
    Keywords : vibration; drilling; chips; aerospace; advanced drilling unit;

    Abstract : This thesis considers vibration drilling in aerospace materials. The tolerances of the drilled holes in aerospace industry are very low since hole quality is an important factor. Conventional methods of drilling create long ribbon formed chips that increases the heat formation and decreases the hole quality. READ MORE

  5. 9. Charge transport in a Hubbard-Holstein junction: Preliminary results from a DFT approach.

    University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Author : Eric Ceccarelli; [2019]
    Keywords : Density functional theory; DFT; Hubbard-Holstein; Hubbard-Holstein model; HH; Quantum transport; Physics and Astronomy;

    Abstract : Many-body systems are extremely complicated to describe due to mutual interactions between the constituent particles. This is for example the case of systems with electron-electron (e-e) and electron-phonon (e-ph) interactions. READ MORE

  6. 10. Numerical analysis of aerodynamic damping in a transonic compressor

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

    Author : Vincenzo Stasolla; [2019]
    Keywords : transonic compressor; flutter; vibration; CFD; transonic kompressor; fladder; vibration; CFD;

    Abstract : Aeromechanics is one of the main limitations for more efficient, lighter, cheaper and reliable turbomachines, such as steam or gas turbines, as well as compressors and fans. In fact, aircraft engines designed in the last few years feature more slender, thinner and more highly loaded blades, but this trend gives rise to increased sensitivity for vibrations induced by the fluid and result in increasing challenges regarding structural integrity of the engine.
