  1. 21. Secondary Fluids Impact on Ice Rink Refrigeration System Performance

    University essay from KTH/Tillämpad termodynamik och kylteknik

    Author : Willem Mazzotti; [2013]
    Keywords : Ice rink; secondary fluid; refrigeration system; thermo-physical properties; heat transfer; pressure drop; model;

    Abstract : Sweden has 350 ice rinks in operation which annually use approximately 1000 MWh each. Therefrigeration system usually accounts for about 43 % of the total energy consumption which is the largestshare of the major energy systems. READ MORE

  3. 22. Long-term Trend of Evapotranspiration in Sweden Affected by Climate Change or Land-use Change.

    University essay from KTH/Biogeofysik

    Author : Wenxin Zhang; [2011]
    Keywords : Evapotranspiration; Rainfall-runoff; CoupModel; HBV; Climate change; land-use change;

    Abstract : Evapotranspiration (ET) is an essential component of water cycle as it is an interlinkage between atmosphere, vegetation and soil surface in terms of energy and water balance. However, whether potential ET has the same tendency to change as actual ET and how ET trend (based on the difference between precipitation and runoff) is directly driven by dominant meteorological factors alone or combined with ecosystem‘s feedbacks to climate change (like land-use change) is still under the discussion.

  4. 23. Modelling and Simulation of Temperature Variations of Bearings in a Hydropower Generation Unit

    University essay from KTH/Energiteknik

    Author : Cotte Gamage Sarathchandra Gunasekara; [2011]
    Keywords : Modelling; temperature; bearing;

    Abstract : Hydropower contributes around 20% to the world electricity supply and is considered as the most important, clean, emissions free and economical renewable energy source.  Total installed capacity of Hydropower generation is approximately 777GW in the world (2998TWh/year). READ MORE

  5. 24. Thermal Simulation of Hybrid Drive System

    University essay from Fluida och mekatroniska system

    Author : Shiva Kumar B M; kathiravan Ramanujam; [2011]

    Abstract : Safety, performance and driving comforts are given high importance while developing modern day cars. All-Wheel Drive vehicles are exactly designed to fulfill such requirements. In modern times, human concern towards depleting fossil fuels and cognizance of ecological issues have led to new innovations in the field of Automotive engineering. READ MORE

  6. 25. Advanced Ray Tracing Techniques for Simulation of Thermal Radiation in Fluids

    University essay from KTH/Mekanik; KTH/Linné Flow Center, FLOW

    Author : Bernhard Semlitsch; [2010]
    Keywords : Thermal radiation; Solar radiation; Solar energy; Heat transfer;

    Abstract : For modeling thermal heat transfer, not only the effects of convection and conduction are relevant, but also thermal and visible radiation. Radiation is especially important for setups with large temperature differences, as well as for interaction with external light sources. READ MORE
