  1. 1. Multiscale Analysis of Multifunctional Composites

    Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Ammara Dil; [2019]
    Nyckelord :;

    Sammanfattning : Conventional polymer composites are highly demanding due to their high strength and stiffness, low weight, easy processing and corrosion resistance. However, their weak out of plane properties restricts their use in high performance applications, such as aerospace, military and automotive components. LÄS MER

  2. 2. Theoretical models of thermal conductivity and the relationship with electrical conductivity for compressed metal powder

    Kandidat-uppsats, Uppsala universitet/Institutionen för teknikvetenskaper; Uppsala universitet/Institutionen för teknikvetenskaper; Uppsala universitet/Institutionen för teknikvetenskaper; Uppsala universitet/Institutionen för teknikvetenskaper; Uppsala universitet/Institutionen för teknikvetenskaper; Uppsala universitet/Institutionen för teknikvetenskaper

    Författare :Sam Tran; Niklas Lindborg; Danilo De Souza Vivedes; Johanna Sjölund; Veronica Enblom; Mattias Sjödin; [2019]
    Nyckelord :;

    Sammanfattning : This Independent Project reviews literature about the effect of pressure and temperature on thermal conductivity in packed beds and its relationship with electrical conductivity. Exploring the relationships between thermal conductivity, porosity and pressure can give useful knowledge for further improvements in manufacturing processes in the field of powder metallurgy.

  3. 3. Towards Paper Insulation Packaging: Evaluation of Thermal and Logistics Performance. A Case Study at HelloFresh

    Master-uppsats, Lunds universitet/Förpackningslogistik

    Författare :Fernando Guardiola Ramírez; [2019]
    Nyckelord :thermal insulation packaging; paper-based; ice melt test; thermography; packaging scorecard; meal kit industry; Technology and Engineering; Agriculture and Food Sciences;

    Sammanfattning : The most common thermally insulated packaging used today is plastic-based and customer behavior towards plastic materials has changed rapidly in recent years. The Meal Kit Industry has a particular need for insulated packaging/cool pouch (CP) and is looking to shift from plastic materials to more paper-based ones. LÄS MER

  4. 4. Thermal Performance Analysis of High Temperature Borehole Thermal Energy Storage Design from an Insulation Perspective

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Teknisk geologi; Lunds universitet/Väg- och vattenbyggnad (CI)

    Författare :Tobias Magnusson; Joel Ljunggren; [2019]
    Nyckelord :High Temperature Borehole Thermal Energy Storage; HT-BTES; Thermal Energy Storage; TRNSYS; Technology and Engineering;

    Sammanfattning : Thermal energy storage is a growing concept within the sector of energy production. The concept is based on storage of excess thermal energy, for usage during high demand, as a mean of reducing the need for new production. LÄS MER

  5. 5. Simulation of Hardening of the MahanaKhon Tower Mat Foundation

    Master-uppsats, KTH/Betongbyggnad

    Författare :Zakaria Kazi-tani; [2019]
    Nyckelord :Hydration; MahanaKhon tower; mat foundation; young concrete; temperature development; thermal stresses; cracking; fly ash; finite element analysis; COMSOL Multiphysics; Hydratation; MahanaKhon tower; bottenplatta; ung betong; temperaturutveckling; termiska spänningar; sprickbildning; flygaska; finita elementanalys; COMSOL Multiphysics;

    Sammanfattning : Cement hydration is the result of a series of simultaneous chemical reactions occurring during the production of concrete. An excessive amount of heat is generated, which consequently may give rise to thermal stresses and cause early age cracks in concrete that may affect its structural integrity, and load bearing capacity.
