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

    University essay from Lunds universitet/Förpackningslogistik

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

    Abstract : 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. READ MORE

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

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

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

    Abstract : 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

    University essay from Mälardalens högskola/Framtidens energi

    Author : Emil Skoglund; [2021]
    Keywords : 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;

    Abstract : 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. READ MORE

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

    University essay from KTH/Energiteknik

    Author : Sezgi Sizmaz; [2016]
    Keywords : ;

    Abstract : 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. READ MORE

  6. 5. Non-dimensional gradient functions for water vapor and carbon dioxide in the marine boundary layer

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Caroline Vahlberg; [2015]
    Keywords : Monin-Obukhov similarity theory; non-dimensional gradient functions; water vapor; carbon dioxide; marine boundary layer; turbulent fluxes; Monin-Obukhov similaritetsteori; dimensionslösa gradientfunktioner; vattenånga; koldioxid; marina gränsskiktet; turbulenta flöden;

    Abstract : A better understanding of the exchange processes taking place over the oceans is of great importance since the oceans cover about 70 % of the Earth’s surface. With better knowledge the turbulent fluxes can be more accurate parameterized, which is essential in order to improve the weather- and climate models. READ MORE
