1. Development of CAD Models for Large Silencer Platforms Using Design Automation
Master-uppsats, Linköpings universitet/ProduktrealiseringSammanfattning : Scania is known as a front-runner in the development of power trains for heavy vehicles, marine, and general industrial applications. As the regulations on emissions for combustion engine vehicles are getting tougher with increasing awareness on sustainable solutions and reducing environmental impact, the goal at Scania is to develop combustion engines to achieve low-pollutant emissions whilst achieving higher efficiency.

2. 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
3. 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
4. Simulation of Combustion in a Hybrid Rocket Engine
Master-uppsats, KTH/Skolan för teknikvetenskap (SCI)Sammanfattning : A numerical investigation on the combustion mechanics of a hybrid rocket engine is performed through unsteady Reynolds-averaged Navier-Stokes simulation. The hybrid rocket engine model is based on an experimental laboratory scale engine design operating on GOX and HDPE as a propellant. LÄS MER
5. A numerical comparison of the thermoacoustics for different equivalence ratios for n-dodecane using LES
Master-uppsats, Lunds universitet/Institutionen för energivetenskaperSammanfattning : Klimatförändringarna påverkar vår värld och det behövs ett mer hållbart samhälle. Flygindustrin är i behov av förändring, men flygmotorer är mycket komplexa och tar tid att utveckla. Termoakustiska instabiliteter har kraften att förstöra en motor, men också att minska miljöpåverkan. LÄS MER
