  1. 21. Characterization of Fiber Orientation and Weld Line Effects in Reinforced Plastics with Reduced CO2eq Emissions

    Master-uppsats, Jönköping University/JTH, Material och tillverkning

    Författare :Anders Tolf; Markus Johannesson; [2022]
    Nyckelord :Fiber-reinforced plastics; GFRP; Reduced carbon dioxide equivalent materials; Experimental; Uniaxial tensile test; Uniform fiber orientation plate; Tensile strength; Fiber orientation; Weld line; Fracture analysis; Microscopy;

    Sammanfattning : With increasing emphasis and regulations on the environmental footprint in industries, the integration of reduced carbon dioxide equivalent (CO2eq) plastic materials is desirable. Fiber-reinforced plastic materials mechanical properties differ with varying fiber orientations. LÄS MER

  3. 22. Optimizing Energy System in a Supermarket : A case study analysis

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Filip Josefsson; [2022]
    Nyckelord :R744; heat recovery; refrigeration system; supermarket; optimization; water-cooled condenser gas cooler; R744; värmeåtervinning; kylsystem; livsmedelsbutik; optimering; vattenkyld kondensor gaskylare;

    Sammanfattning : With more restrictions regarding the use of refrigerants with high GWP-values, refrigeration systems that uses R744 (Carbon dioxide) as a refrigerant increases. Supermarkets are energy intense facilities where the refrigeration system utilize a significant part of the total utilized energy. LÄS MER

  4. 23. Wind Farm Modeling in DIgSILENT PowerFactory® and Load Flow Analysis of Internal Collector Network

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Lakshitha Daham Makewita; [2022]
    Nyckelord :Wind Farm Internal Collector Network; Active Power Loss; Cable Loading;

    Sammanfattning : The purpose of this study is to model an operational wind farm in DIgSILENT PowerFactory® using manufactures specifications and investigate the active power energy losses. The model is tested with the operational recorded data from the wind farm and is validated. LÄS MER

  5. 24. Solceller på Västergårdsgymnasiet : En förstudie för att implementera solceller och energilagring ur ett ekonomiskt perspektiv

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Byggteknik och byggd miljö

    Författare :Tim Gyulanszky; [2022]
    Nyckelord :solceller; energilagring; vätgas; litium-jon; flödesbatteri;

    Sammanfattning : The purpose of the project was to carry out a study of a potential solar cell facility at Västergårdsgymnasiet. Previous studies have established that there is the greatest potential for electricity production during the summer period, which coincides with the load at its lowest. LÄS MER

  7. 25. Understanding the correlation between molecular structure of chilled dairy creams and the risk of environmental stress cracking in Tetra Pak® carton packages

    Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)

    Författare :Alejandra Fernandez Castaneda; [2022]
    Nyckelord :Cream; microestructure; environmental stress cracking; food technology and nutrition; Agriculture and Food Sciences;

    Sammanfattning : Multilayer food packaging are lined with an inner layer of plastic and has excellent barrier properties. However, plastics lose their mechanical properties after being exposed to certain conditions; the combination of factors generates failures in the material such as the appearance of cracks, this phenomenon is known as environmental stress cracking (ESC).
