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. Propulsion modelling of a generic submarine propeller
Master-uppsats, KTH/Skolan för teknikvetenskap (SCI)Sammanfattning : Self propulsion modelling is important in order to accurately simulate ships and submarinesusing Computational Fluid Dynamics (CFD). However, fully resolved simulations of hull andpropeller geometries are computationally heavy and time consuming. As such there is a greatinterest in lower order CFD models of propellers. LÄS MER
3. Experimental Study of Flow Fields in Moving Bed Biofilm Reactors
Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknikSammanfattning : With the rise in global energy prices, as well as energy consumption being the largest source of greenhouse gas emissions, biofilm-based systems utilized for wastewater treatment, such as moving bed biofilm reactors (MBBRs), have grown in popularity for their lower energy consumption compared to conventional activated sludge processes. However, this technology requires large amounts of energy to constantly distribute and suspend its biofilm carrier within the reactor by either aerators or mechanical mixers. LÄS MER
4. Computational Analysis of Spray Deflector Designs
Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanikSammanfattning : Planing hull is a common hull design concept which decreases the resistance while speed is increasing for a specific speed range. It is also suitable for hull modifications to achieve higher efficiency. Spray deflector is a promising hull modification which offers extra resistance decreasing and less vertical acceleration for planing hulls. LÄS MER
5. Hydrogen-Methane combustion modeling in the burner of the SGT-800 Siemens Energy gas turbine
Master-uppsats, KTH/Teknisk mekanikSammanfattning : Industrial gas turbines constitute an integral part of today’s electricalpower production infrastructure. Reacting gas flows in these machines arevery interesting and complex in nature since they exhibit highly turbulentbehaviour which is strongly coupled to the chemical reaction dynamics. LÄS MER
