  5. 4. Techniques to inject pulsating momentum

    University essay from Luleå tekniska universitet/Strömningslära och experimentell mekanik

    Author : Jelle Kranenbarg; [2020]
    Keywords : Hydro power; Rotating Vortex Rope; Flow control; Fluidic actuator; Synthetic jet actuator; Piston actuator; CFD;

    Abstract : Hydro power plants are an essential part of the infrastructure in Sweden as they stand for a large amount of the produced electricity and are used to regulate supply and demand on the electricity grid. Other renewable energy sources, such as wind and solar power, have become more popular as they contribute to a fossil free society. READ MORE

  6. 5. Digital Compensation of Phase Noise Caused by Mechanical Vibrations

    University essay from Uppsala universitet/Institutionen för teknikvetenskaper

    Author : Akib Mahmud; [2019]
    Keywords : ;

    Abstract : The component that generates the frequency of the radio waves transmitted by a radar is generally built around a quartz crystal oscillator. When this component is exposed to mechanical vibrations, such as acceleration or rotation in different directions, phase noise occurs. READ MORE
