  1. 6. Effects of cracking of coupling beams onhigh rise towers subjected to wind load

    University essay from KTH/Betongbyggnad

    Author : Brook Worku Woldemikael; [2020]
    Keywords : Crack; reinforcement content; aspect ratio; shear deformation; joint flexibility; concrete grade; effective stiffness.; Sprickor; förstärkningsinnehåll; tvärsnittsförhållande; skjuvdeformation; ledflexibilitet; betongkvalitet; effektiv styvhet;

    Abstract : In high rise towers, reinforced concrete elevator shafts with coupling beams are extensively used as a principal structural element to resist lateral loads. The lateral load resistance of the tower is dominantly dependent on the stiffness of the load-bearing walls, and coupling beams connecting them. READ MORE

  3. 7. Techno-Economic Analysis of an Innovative Purely Solar Driven Combined Cycle System based on Packed Bed TES Technology

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Tianqi Ruan; [2019]
    Keywords : Tower CSP Techno-economic analysis; Dynamic simulation; Tower CSP teknisk-ekonomisk analys; Dynamisk simulering;

    Abstract : With increasing awareness of environmental issues and worldwide requirements for sustainable development, renewable energy technologies with lower environmental impact, especially those having abundant resources like wind and solar energy, attract more attention. Concentrating Solar Power (CSP) is one of the most promising solar energy technologies. READ MORE

  4. 8. Experimental investigation of a de-icing system for wind turbine blades based on infrared radiation

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Sofia Sollén; Jennifer Pettersson; [2019]
    Keywords : Wind power; Wind turbine; Cold climate; Ice and snow; De-icing; De-icing system; Infrared radiation; Infrared heater.;

    Abstract : Wind power is one of the fastest growing production methods of electric energy. The expansion of wind power in Sweden are focused to northern counties. There are advantages as good wind conditions and large unexploited areas to build wind farms in the north, but there are also problems caused by the long winters. READ MORE

  5. 9. Nocturnal jets in Skåne: an analysis of data from Hyltemossa research tower

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Förbränningsfysik

    Author : Tove Fast; [2019]
    Keywords : Physics and Astronomy;

    Abstract : A nocturnal jet is a low level air jet that is often seen at an altitude below 500 m during night time conditions. It can reach wind speeds of storm force and is thus of importance for aviation and also for transport of e.g. moisture and pollutants in the lower troposphere. READ MORE

  6. 10. Predicting the Momentum Flux-Profile Relationship from Macro Weather Parameters

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Emilio Dorigatti; [2018]
    Keywords : ;

    Abstract : The study of climate heavily relies on simulations. For efficiency reasons, many important phenomena cannot be simulated, and have to be parametrized, i.e. their effect must be described based on macro parameters. READ MORE
