  1. 1. Mitigation of Pressure Pulsations in Axial turbine draft tube with jet injection or solid rod protrusion: A Numerical investigation

    Författare :Henrik Holmström; Cécile Münch-Alligné; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vortex rope mitigation; vortex rope; Strömningslära; Fluid Mechanics;

    Sammanfattning : The introduction of intermittent renewable energy sources, such as wind and solar power, to the power grid, demands some hydraulic turbines to operate at unfavorable operating conditions not initially designed for. Strong swirl develops at loads below the best efficiency point, (BEP) due to angle mismatch between the guide vanes and the fixed runner blades typical for Francis and Propeller turbines. LÄS MER

  3. 2. Mitigation of Pressure Pulsations in Francis Turbine Draft Tube with a GuideVane System : A Numerical Investigation

    Författare :Jesline Joy; Michel Cervantes; Cécile Münch-Alligné; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Computational fluid dynamics; Francis turbine; Part load; Reduced modelling; Rotating vortex rope; Strömningslära; Fluid Mechanics;

    Sammanfattning : The use of renewable energy such as water and wind to produce electricity has been proven extremely effective in Sweden. The ability of these renewable resources to produce clean output energy counters the adversities caused by non-renewable resources. LÄS MER

  4. 3. Mitigation of Rotating Vortex Rope in a Hydro Turbine using a Guide Vane System

    Författare :Jesline Joy; Michel Cervantes; Mehrdad Raisee; Cécile Münch-Alligné; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Sammanfattning : Using renewable energy, such as water or wind, to produce electricity has been proven highly effective in Sweden. The ability of these renewable resources to make clean output energy counters the adversities caused by non-renewable resources. Amongst these, hydro turbines are one of the most preferred methods for generating electricity from water. LÄS MER
