1. Optimization of Radiotherapy Treatment Plans Based on Monte Carlo Dose Computations
Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknikSammanfattning : Treatment planning plays a vital role in providing good treatment to cancer patients. In order to reach an adequate treatment plan, the algorithm used for simulating the dose in the patient must model the reality well. LÄS MER
2. Implementation of Large-scale Grid Storage in Malmö
Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Miljö- och energisystemSammanfattning : Denna rapport undersöker möjligheten till implementering av en storskalig energilagringslösning i Malmö och dess effekt på elbalansen. Arbetet utgår från Texel Energy Storage AB:s termokemiska batterilösning som lagrar energi i form av värme, vilken sedan utvinns som elektrisk energi genom en Stirlingmotor. LÄS MER
3. Reprocessing and Characterization of Polybenzimidazole for High-Temperature Polymer Electrolyte Membrane Fuel Cells
Master-uppsats, Lunds universitet/Centrum för analys och syntesSammanfattning : A reprocessing method of poly(2,2’-(m-phenylene)-5,5’-bibenzimidazole) (PBI) membranes recovered from the production line of High-Temperature Polymer Electrolyte Membrane Fuel Cells (HT-PEMFC) at Blue World Technologies (BWT) has been developed in order to reduce material loss in the production. Redissolution of scrap PBI membranes in poly(phosphoric acid) (PPA) and phosphoric acid (PA) was successful and the subsequent washing procedure produced PBI that could be redissolved in N,N-dimethyl acetamide (DMAc) and suitable for solution casting of new membranes.

4. CFD investigation of a unit cell inside a Plate Heat Exchanger
Master-uppsats, Lunds universitet/Institutionen för energivetenskaperSammanfattning : A numerical investigation of the unit cell approach has been done to reduce the computational cost for CFD (Computational Fluid Dynamics) of plate heat exchangers (PHE) at Alfa Laval. The reduced cost would enable LES (Large Eddy Simulation) to be done which would give a more detailed and accurate insight into the flow and heat transfer processes of the PHE. LÄS MER
5. Design of Experiment Based on Full Factorial CFD Spray Modelling
Master-uppsats, Lunds universitet/Institutionen för energivetenskaperSammanfattning : Design of experiment is a powerful tool that can reduce the amount of physical testing needed to save resources, time and money. A CFD-setup was constructed in OpenFOAM-8, simulating injection of liquid propane with a standard multi-hole injector. The model was then validated against experimental results. LÄS MER
