21. Analytical prediction of turbocharger compressor performance: A comparison of loss models with numerical data
University essay from KTH/Maskinkonstruktion (Inst.)Abstract : One-dimensional models predict the performance of centrifugal compressor in short time, being a helpful design tool in the early design stages. They assume uniform flow through the compressor. Conservation of mass, momentum and energy and some empirical loss correlations are applied to estimate the real outputs. READ MORE

22. Numerical Modelling of a Radial Inflow Turbine with and without Nozzle Ring at Design and Off-Design Conditions
University essay from KTH/EnergiteknikAbstract : The design of a radial turbine working at peak efficiency over a wide range of operating conditions is nowadays an active topic of research, as this constitutes a target feature for applications on turbochargers. To this purpose many solutions have been suggested, including the use of devices for better flow guidance, namely the nozzle ring, which are reported to boost the performance of a radial turbine at both design and off-design points.

23. Sediment transport in Säveån and its implications for erosion and bank stability
University essay from Lunds universitet/Avdelningen för Teknisk vattenresursläraAbstract : This master thesis study is a preliminary investigation of the Säveån River as part of the Swedish Geotechnical Institute’s (SGI) landslide risk assessment project. The main objectives include building a hydrodynamic model for the river, estimating sediment transport along the river, assessing the implications for erosion and bank stability and evaluating climate change effects on sediment transport.

24. Epitaxial growth of Sn seeds and Sn-seeded InSb nanowires on InSb substrates
University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionenAbstract : During the last decades, researchers have done extensive research on one-dimensional structures because of their promising properties for a broad range of applications. However, there are a few factors slowing down the process of integrating these nanowires in commercial products. To overcome this, new material combinations are being explored. READ MORE

25. Sensitivity of sediment transport on river characteristics in the large, braided Brahmaputra River
University essay from Stockholms universitet/Institutionen för naturgeografiAbstract : Erosional issues in the Brahmaputra River in the eastern Himalayas pose increasing pressure on the nearby societies and ecosystems. With a proceeding climate change and increasing anthropogenic disturbance, predictive models are needed to evaluate the effect on sediment transport. READ MORE
