  2. 21. Experimental investigation of premixed ammonia combustion at high Karlovitz number conditions

    Author : Qingshuang Fan; Förbränningsfysik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Turbulent premixed combustion; Ammonia flames; Laser diagnostics; Flame structure; High Karlovitz number; Turbulent burning velocity; Fysicumarkivet A:2021:Fan;

    Abstract : This thesis aims to acquire deep knowledge on turbulent premixed combustion at high Karlovitz (Ka) number conditions with the help of laser-based diagnostic measurements.Considering that ammonia (NH3), as a carbon-free energy carrier, is a promising candidate for replacing conventional fossil fuels in the future, all the investigations in this work were carried out on ammonia/air premixed flames.

  4. 22. Efficient Integration of Distributed Generation in Electricity Distribution Networks - Voltage Control and Network Design

    Author : Ingmar Leisse; Industriell elektroteknik och automation; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Coordinated Voltage Control; Distributed Generation; Electricity meter; PV; Wind Power; Distribution Network;

    Abstract : Distributed generation (DG), i.e. generation connected to the low and medium voltage distribution network (DN), has been increasing a lot during recent years. Thus the traditional assumption of a unidirectional power flow and a voltage decrease along the distribution feeders is no longer valid in all operation conditions. READ MORE

  5. 23. The evolution of upper Norrland's ports and loading places 1750-1976

    Author : Ian G. Layton; Umeå universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; communications patterns; economic development; export trade; forest-based industries; historical geography; industrial location; northern sweden; port evolution; ports; transport technology;

    Abstract : Models of port development have hitherto concentrated on landward communications and the organization of maritime space in their explanation of changes in port location and activity. This study demonstrates that the level of economic development in hinterlands together with industrial and marine technology are also significant factors and indeed play leading roles in the process of port evolution.

  6. 24. Planning and Operation of Large Amounts of Wind Power in a Distribution System

    Author : Shemsedin Nursebo; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cost benefit analysis; coordination.; distribution system; active management strategies; control; integration issues of wind power; frequency of tap change;

    Abstract : The global installed capacity of wind power has shown a significant growth, from 24 GW in 2001 to 370 GW in 2014. The trend shows that an increasing capacity of wind power is being connected to the electric power system. READ MORE
