1. Test rig for evaluation of protective coating against molten aluminum
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : Today, many methods test the lifetime of coatings, but none focus on testing protective coatingsin a non-oxidizing environment. Hence, this master thesis developed a method to test the life-time of a protective coating against molten aluminum. LÄS MER
2. Thermal and flow field validation of lattice Boltzmann method solver
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikSammanfattning : Computational fluid dynamics, abbreviated CFD, is a valuable tool for several engineering applications. Applications such as heating, cooling or drying are some examples of areas where CFD is used. LÄS MER
3. Renovering av kulturhistoriskt värdefull bebyggelse med hänsyn till energieffektivisering
Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Avdelningen för ByggnadsfysikSammanfattning : The aim of this study was to provide proposals for renovation measures and investigate to what extent preservation of cultural values can be combined with energy efficiency in an urban transformation projects. The goal was also to develop a strategy for the renovation of k-marked buildings using literature study, case study and parameter study. LÄS MER
4. Förbättring av energieffektiviteten för villor genom att implementera grund geotermisk ventilation
Kandidat-uppsats, Jönköping University/JTH, Byggnadsteknik och belysningsvetenskapSammanfattning : Introduction: The world is facing an economic crisis that has led to high energy prices in the EU. These high energy prices have been a contributing factor to the challenging economic situation in Sweden, affecting businesses, industries, and households. EU countries have limited access to energy and rely mostly on imports. LÄS MER
5. Free cooling and PVT integration in a ground-source heat pump (GSHP) system
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : The performance of ground-source heat pump (GSHP) systems can be negatively affected over time by soil temperature degradation of boreholes (BH) in heating dominated climates. Land area is scarce in the dense urban environments typical of multi-family houses (MFH) and can lead to accelerated degradation- in tight BH fields. LÄS MER
