  1. 21. Simulation of solidification and cooling of a casting product using COMSOL Multiphysics

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Tom Allen; [2019]
    Keywords : Heat transfer; casting; phase change; COMSOL Multiphysics; Technology and Engineering;

    Abstract : In this project, the cooling and solidification processes for a Valmet Foundry product have been simulated in order to shorten the cooling time. The study has also been done in cooperation with RISE Swecast in Jönköping, as a part of finding ways to make casting procedures more energy efficient. READ MORE

  3. 22. Energy balance closure, water balance, carbon exchange, and water use efficiency : observed and modeled outcomes for a managed, hemiboreal forest in Southern Sweden

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Linsey Marie Avila; [2019]
    Keywords : Energy balance; energy balance closure; energy balance ratio; net radiation; sensible heat; latent heat; turbulent fluxes; ground heat flux; energy storage; available energy; Bowen ratio; evaporative fraction; latent heat of vaporization; water balance; evapotranspiration; precipitation; water storage; water discharge; gross primary production; ecosystem respiration; net ecosystem production; carbon exchange; water use efficiency; Earth and Environmental Sciences;

    Abstract : The claims for the potential of boreal and sub-boreal forests to combat negative effects of climate change have been substantial with over half of Earth’s primary forests found within boreal and temperate regions of the Northern Hemisphere. Given the likely occurrence of more extreme climate events in the future, ascertaining a better understanding of how climate effects, such as profound fluctuations in precipitation, decreases in yearly snow, faster snow melt rates, variability in evapotranspiration due to environmental stress, and related changes in the energy, hydrological, and carbon cycles will change these northern, boreal landscapes is crucial.

  4. 23. Uppvärmning av Almunge brandstation med pyrolys

    University essay from SLU/Dept. of Energy and Technology

    Author : Felix Eriksson; Erik Gustafsson; Karl Malmberg; Simon Martelius; Simon Johansson; Patrick Johansson; Michael Stanowski; [2019]
    Keywords : biokol; trädgårdsavfall; brandstation; värmeförsörjning; jordförbättringsmedel; pyrolysreaktor;

    Abstract : This project has been carried out on the behalf of Ihus in collaboration with Stuns Energi. The goal was to find and model a solution based on the process of pyrolysis that can deliver enough heat to Almunge fire station while storing maximum amount of CO2 in the form of biochar. READ MORE

  5. 24. Modelling heat recovery from urban wastewater systems - case study from Malmö

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Diego Reyes; [2019]
    Keywords : Heat; Recovery; Wastewater; City; Wide; Model; Urban; Sustainability; Sewer; System; Malmo; Temperature; Sweden; Water engineering; Environmental engineering; Vattenförsörjningsteknik; Avloppsteknik; Technology and Engineering;

    Abstract : The purpose of this thesis is to estimate how much heat can be recovered from the sewer system in Malmö, Sweden, and determine the best location for that heat recovery. In fulfilling that purpose, this thesis covers the process of modeling wastewater flows and temperature changes in the sewer system in Malmö, the results of those processes, and the estimated amount of heat that can be recovered from the sewer system.

  6. 25. Design benefits with Additive Manufacturingfrom a convective heat transfer perspective

    University essay from KTH/Flygdynamik

    Author : Joakim Storfeldt; [2019]
    Keywords : ;

    Abstract : Nowadays manufacturing processes are rapidly developing. Salt-bath dip brazing is a conventional manufacturing method commonly used by Saab AB to fuse aluminium components in a high temperature salt bath. However conventional manufacturing methods have shown some limitations. READ MORE
