1. Techno-economic analysis and simulation of low temperature district heating networks
Master-uppsats, Lunds universitet/Avdelningen för Energi och byggnadsdesign; Lunds universitet/Institutionen för arkitektur och byggd miljöSammanfattning : The continuous increase in global energy consumption has led to a greater focus on the energy required for heating buildings. This thesis presents a techno-economic model for analysing low-temperature district heating networks coupled with a geothermal heat source. LÄS MER
2. Evaluating a new hydraulic implementation in LPJ-GUESS for three sites in north Europe
Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapSammanfattning : Drought is projected to increase in frequency and intensity and impacts trees with increased water stress and increased mortality rate. Water stresses can cause hydraulic failure-related mortality or carbon starvation due to tree species having different strategies to deal with water stresses. LÄS MER
3. Hydraulic modelling at Finsjö Övre hydropower plant : Study for evaluation of a fishway's attractiveness
Master-uppsats, Umeå universitet/Institutionen för tillämpad fysik och elektronikSammanfattning : In connection with the government’s approval on the proposed national plan (NAP) in 2019, it has become highly topical to find solutions problems regarding fish migration in Swedish watercourses. At Finsjö Övre hydropower plant in Emån, a new type of fishway is planned to be installed and evaluated starting at the end of 2022. LÄS MER
4. Thermal-hydraulic safety analysis of the HTTU and GEMINI+ cores in TRACE
Master-uppsats, KTH/FysikSammanfattning : With the coming of Generation IV systems, there is a need for thermal-hydraulic codes to model such advanced reactors. Codes for High Temperature Gas-cooled Reactors (HTGRs) already exist, but often suffer from insufficient validation and little user experience. LÄS MER
5. Simulation of IB-LOCA in TRACE : A semi-blind study of numerical simulations compared to the PKL test facility
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad kärnfysikSammanfattning : This thesis studied the performance of the thermal hydraulic software TRACE applied on an intermediate sized break (IB) happening on the cold leg in a pressurized water reactor (PWR), causing a loss-of-coolant accident (LOCA). The same accident has previously been simulated in the PKL Test Facility, which is a scaled version of a PWR and is used to simulate transients stemming from different accidents. LÄS MER
