  1. 1. Towards Sustainable Coffee Packaging: A Comparative Study of Current and Future Materials for Zoégas Coffee

    Master-uppsats, Lunds universitet/Förpackningslogistik

    Författare :Alexandra Karlsson; [2023]
    Nyckelord :Food packaging; coffee; permeability; recyclability; shelf life.; Technology and Engineering;

    Sammanfattning : An important factor in preventing food waste is the ability to provide a product with a package according to its needs. The packaging material, in turn, needs to be recyclable in order to contribute to a circular use of materials rather than becoming waste. LÄS MER

  3. 2. Co-Simulation Development for Improved Cavitation Predictions in Oil-Hydraulics Systems : An investigation into the cavitating flow behavior of repetitive water hammers.

    Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

    Författare :Thisal Mandula Sugathapala; Twan Bakker; Rahul Gudur Suresh; Aryan Delir; [2022]
    Nyckelord :co-simulation; water hammer; cavitation;

    Sammanfattning : Numerical modeling of cavitation using computational software is a highly pursued topic of research due to its impact in different industrial sectors. While some industrial applications such as wastewater treatment and mineral processing are known to advantageously use this phenomena, it remains an unwanted process in others where it is known to induce vibration, reduce performance and cause structural damage.

  4. 3. A NUMERICAL MODEL OF HEAT- AND MASS TRANSFER IN POLYMER ELECTROLYTE FUEL CELLS : A two-dimensional 1+1D approach to solve the steady-state temperature- and mass- distributions

    Uppsats för yrkesexamina på avancerad nivå, Mälardalens högskola/Framtidens energi

    Författare :Emil Skoglund; [2021]
    Nyckelord :PEFC; PEM; convection; mass transport; heat transport; co-flow; temperature profile; heat transfer model; transient; steady state; water concentration profile; water vapor profile; relative humidity; through-plane cross section;

    Sammanfattning : Methods of solving the steady state characteristics of a node matrix equation system over a polymer electrolyte fuel cell (PEFC) were evaluated. The most suitable method, referred to as the semi-implicit method, was set up in a MATLAB program. LÄS MER

  5. 4. Fuktberäkningar i fogbetongen mellan håldäcksplattor : En analys av det ekvivalenta mätdjupet

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

    Författare :Rohollah Akhlaqi; Jon Momqvist; [2021]
    Nyckelord :Beräkningar; Ekvivalent mätdjup; Fogbetong; HD F-platta; WUFI Pro; Fuktprofil; Torka S; Simulering; RBK; Uttorkning.;

    Sammanfattning : This thesis covers calculations of the equivalent measuring depth in the joint concrete between hollow-core slabs performed using the calculation and simulation program WUFI Pro. The calculations are based on input data from field measurements performed by Polygon|AK in Uppsala. LÄS MER

  7. 5. Optimization of a small-scale polygeneration energy system for a household in Turkey

    Master-uppsats, KTH/Energiteknik

    Författare :Sezgi Sizmaz; [2016]
    Nyckelord :;

    Sammanfattning : With environmental concerns, alternative solutions for generating electricity while decreasing the consumption of fossil fuels have gained a great importance. Polygeneration is one of these solutions which is also capable to increase the technical performance of electricity generation. LÄS MER
