    Författare :Mohsen Bayat Pour; Mohammed Labib Elsayed; [2020]
    Nyckelord :Bio-based Materials; Fossil-based Materials; Building Performance Simulations; Energy analysis; Environmental impact categories; Life cycle assessment LCA ; Economic analysis; Life cycle costing LCC ; Global warming potential; Climate change; Future climate analysis; Timber structure; Concrete structure; Insulation; HVAC systems; Heating demand; Cooling demand; Energy use; Hygrothermal analysis; Moisture; Thermal envelope; Thermal comfort; Indoor environmental quality; Actual case studies; Iterative workflow; Weather files; Parametric study; Reliability; Single-point rate SPR .; Technology and Engineering;

    Sammanfattning : Increasing CO₂ emission is considered as the main reason for global warming in the world. One of the reasons for producing CO₂ is using of fossil-based materials in the construction projects. LÄS MER

  2. 2. Reinforcement Layout in Concrete Pile Foundations : A study based on non - linear finite element analysis

    Master-uppsats, KTH/Betongbyggnad

    Författare :Mohammad Mustafa Angar; [2020]
    Nyckelord :Pile cap; Nonlinear finite element analysis; ATENA 3D; Reinforcement layout; Strut and tie method; Pålfundament; icke-linjära finita elementmodeller; strut and tie-metoden;

    Sammanfattning : The main topic of this thesis concerns the behavior of concrete pile cap supported by four piles with two varying positions of longitudinal reinforcements. The positions include top of piles and bottom of the pile cap. For this purpose, non-linear finite element models of a pile cap are created using software ATENA 3D. LÄS MER

  3. 3. Creating a Dynamic Model of a Gas Turbine in the MVEM Framework Using an Ellipse Compressor Model

    Master-uppsats, Linköpings universitet/Fordonssystem

    Författare :Edvin Hansson; [2020]
    Nyckelord :Gas turbine; Modeling; control;

    Sammanfattning : The legislations on greenhouse gas emissions are getting tougher and tougher every year. This drives the demand for energy efficient gas turbines with as low emissions as possible. This poses the challenge to manufacturers of constructing gas turbines with lessened environmental impact, but with maintained performance. LÄS MER

  4. 4. Finite element modelling of LV transformer winding to simulate dynamic events occurring under short circuit : In Ansys Mechanical

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Författare :Madhu Venkata Sri Prudhvi Bikkina; [2020]
    Nyckelord :Ansys Mechanical; LV winding; Power Transformer; Short-circuit; Spiraling; Torsional Mode Shapes;

    Sammanfattning : The ability to withstand a short circuit is the most essential feature of a power transformer. The most important reason to design short-circuits proof transformers is to ensure the reliability of the power grid (avoiding black outs etc.) and safety (fire and explosion in case of failure).

  5. 5. Modelling and Simulation of Fan Performance using CFD Group

    Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

    Författare :Shreyasu Subramanya; [2020]
    Nyckelord :CFD; Centrifugal compressor; Vacuum;

    Sammanfattning : Performance of vacuum cleaners are affected by factors such static pressure, airflow rate and efficiency. In this thesis work, attempt has been made to design a fan to meet the requirements of suction static pressure and air flow rate and in the process understand the fan design parameters that affect these performance parameters.
