1. 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

   University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

   Author : Wilma Fager; Maja Abrahamsson Bolstad; Emma Gustafsson; Emma Andersson; Matilda Eriksson; [2023]
   Keywords : GREC; Energy; Heat transfer; Heat rate; Temperature distribution;

   Abstract : 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. READ MORE

3. 2. Sensitivity Analysis and Optimization of the Vertical GSHP (Ground source heat pump)

   University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

   Author : Sriram Ramanathan; [2020]
   Keywords : GSHP; Borehole heat exchanger; Geo-thermal energy.;

   Abstract :   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. READ MORE

4. 3. Oil Cooling of Electric Motor using CFD

   University essay from KTH/Tillämpad termodynamik och kylteknik

   Author : Kamilla Al Shadidi; [2014]
   Keywords : Electric motor; Oil cooling; CFD; Multiphase flow; Fluid film; Lagrangian multiphase flow;

   Abstract : 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. READ MORE

5. 4. Modeling and evaluation of laminated windings

   University essay from Lunds universitet/Industriell elektroteknik och automation

   Author : Rasmus Kjellstrand; Ville Akujärvi; [2013]
   Keywords : Technology and Engineering;

   Abstract : 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. READ MORE

6. 5. Controls of seafloor depth on hydrothermal vent temperatures : prediction, observation & 2D finite element modeling

   University essay from Lunds universitet/Geologiska institutionen

   Author : Christine Andersen; [2010]
   Keywords : porous convection; compressible fluid flow; boiling; mixing; low heat supply; conductive heat flow; porös konvektion; kompressibelt flöde; kokning; blanding; lågtempererad värmekälla; konduktivt värmeflöde; Earth and Environmental Sciences;

   Abstract : Circulation of hot hydrothermal fluids in fractures and faults of the oceanic crust is driven by temperature and pressure gradients. Fluid discharge is focused to vertical structures, black or white smoker chimneys on the seafloor. Hydrothermal vent temperatures should hypothetically be directly related to water depth. READ MORE
