1. Thermal Investigation of the Green Revolution Energy Converter : A study on the heat transfer within the GREC in regards of temperature distribution and heat rate
L3-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningsläraSammanfattning : To reduce emissions, new technological solutions can be of use. One technology which is currently being developed is the Green Revolution Energy Converter, GREC. GREC is an engine with the aim to produce electricity from temperature gradients. This project is part of a greater project that is divided in two with different focus areas. LÄS MER
2. Validering av solida temperaturer i FDS genom jämförelse mot FE-beräkningar
Uppsats för yrkesexamina på grundnivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurserSammanfattning : FDS (Fire Dynamics Simulator) använder en version av Navier-Stokes ekvationerna för att göra noggranna beräkningar av värme- och gastransport genom brandbelastade utrymmen. Utvecklarna av programmet arbetar kontinuerligt med att validera det allteftersom nya funktioner tillförs för att öka noggrannheten och bredda tillämpningsområdena. LÄS MER
3. Sensitivity Analysis and Optimization of the Vertical GSHP (Ground source heat pump)
Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningsläraSammanfattning : GSHP (Ground source heat pump), uses geothermal energy which is a form of green and sustainable energy. Geothermal energy is also a continuous source of energy, unlike wind energy. The results from this thesis work will be applicable for both GSHP that are being used for space heating, and the ones which have a bottom organic Rankine cycle. LÄS MER
4. Oil Cooling of Electric Motor using CFD
Master-uppsats, KTH/Tillämpad termodynamik och kylteknikSammanfattning : This thesis investigated the heat transfer of internally oil cooled rotors in permanent magnet electric machines which are, among other things, used in hybrid vehicles or zero emission vehicles. The magnets become sensitive and can be demagnetized at high working temperatures, hence the need of cooling. LÄS MER
5. Modeling and evaluation of laminated windings
Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell elektroteknik och automationSammanfattning : Electrical machines in electrical vehicles are sometimes put under a lot of stress when for example climbing an uphill road. In order for the machine to cope with the heat generation that comes of running extended periods of time near or at peak power one needs a highly developed cooling system. LÄS MER
