11. Investigation of new refrigerants for a large-scale heat pump and evaluation of system performance
Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningsläraSammanfattning : Heat production accounted in 2021 for 50 % of the energy end use globally, where a strongconnection to fossil sources still exists. Large-scale electrical heat pumps can therefore have akey role in the energy system to enable a decreased reliance on fossil fuels and at the same timecontribute to stable system when incorporating more intermittent renewable sources.

12. Development of an Accelerated Test Method for Compressed Natural Gas Fuel System Robustness against Contamination
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikSammanfattning : A key factor for driving the shift towards sustainable transportation systems is alternative fuels, where compressed natural gas (CNG) is a beneficial alternative to the conventional fossil fuels with respect to greenhouse gas emissions. A fuel system is needed for heavy-duty natural gas vehicles, in order to transport the highly pressurized gas from the fuel tanks to the internal combustion engine. LÄS MER
13. Forced response numerical investigation of a transonic compressor rotor
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : The present thesis discusses the forced response of a rotor’s bladed-disk when excited by the periodic force produced by a wake generator, or Inlet Guide Vane (IGV),with 8 equally-spaced blades. These components are part of an axial transonic compressor rig, moreover the Transonic Compressor Darmstadt 1 (TCD1), located at the Technical University of Darmstadt. LÄS MER
14. Data-driven modelsfor estimating heatpump powerconsumption
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : The number of installed heat pumps has been rapidly increasing in recent years, acceleratingthe decarbonisation of the heating sector. The impact of the increasing deployment of heatpumps on the grid can be evaluated with the help of models estimating the heat pumppower consumption. LÄS MER
15. RF Compressor (SLED) Phase-Modulation to Reduce Peak Fields in the MAX IV Linear Accelerator
Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknikSammanfattning : Modern particle accelerators need strong electric fields in order to produce high energy particles. Such high voltages are typically reached by injecting pulsed radio frequency power through several steps of amplification. At the end, pulse compression is used to further improve the energy gain at the cost of pulse-length. LÄS MER
