   Sammanfattning : Switches and crossings are vital components of the railway network. Obstacles to the smooth functioning of these components could result in delays and network traffic. Given the geographical location of Sweden, snow is one of the major obstacles for the switches. LÄS MER

3. 2. Experimental Investigation of Hydrodynamic Effects on a Vibrating Kaplan Runner

   Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Strömningslära och experimentell mekanik

   Författare :Jakob Hedlund; [2017]
   Nyckelord :FSI; fluid-solid interactions; Kaplan runner; hydrodynamic; added mass; added damping; vibrations;

   Sammanfattning : An experimental investigation of a vibrating Kaplan turbine runner was performed in order to understand the hydrodynamic effects and to obtain or confirm the mass and damping coefficients used for dimensioning at the design stage. Improved design can lead to increased efficiency and lifetime of hydropower stations. LÄS MER
