  1. 16. Optimal collection grid and transmission line topology for the grid connection of an offshore multi-source park.

    University essay from Uppsala universitet/Elektricitetslära

    Author : Alfred Nerby; [2022]
    Keywords : Renewable; Wind; Solar; multi-source; park; collection grid; substation; transmission; HVAC; HVDC; converters; shunt reactors; transformer; losses; CAPEX; OPEX;

    Abstract : As spacial restrictions become more and more of an issue for renewable energy parks onshore, more developers are turning offshore to develop future production. The desire for a diversity of energy sources combined with a desire to utilize space efficiently has sparked an interest in renewable energy parks where more than one energy source occupy the space.

  5. 19. Fluid/Material Coupled Numerical Analysis of Single Bubble Collapse Near a Pit on a Wall

    University essay from KTH/Strömningsmekanik och Teknisk Akustik

    Author : Daiki Makii; [2020]
    Keywords : Bubble Dynamics; Cavitation Erosion; Numerical Analysis; Fluid Material Coupled Numerical Method; Homogeneous Model; Elastic Body Material; Erosion Pit;

    Abstract : In order to elucidate the progression mechanism of cavitation erosion, the behaviors of a single cavitation bubble collapse near a pit on a wall and both the resulting pressure wave in fluid and stress wave in material are investigated in detail. To find out the mechanism of cavitation erosion, many experimental studies on the bubble collapse behavior near a flat rigid wall and the resulting material damage have been conducted so far.
