1. Practical investigation of mixing phenomena by physical modelling : Scaling criteria applied for bottom gas-stirred water modelling of metallurgical vessels
Kandidat-uppsats, KTH/MaterialvetenskapSammanfattning : Gas stirring is currently the most commonly used method of homogenizing liquid steel in commercial processes. However, due to the harsh environment during the process, physical models built out of e.g. plexiglass have been used to easier understand the complex phenomenon occurring in the process. LÄS MER
2. Investigation of the scale factor between full scale ladle furnace process and water models
Kandidat-uppsats, KTH/MaterialvetenskapSammanfattning : The ladle furnace process is an important process in the steel manufacturing industry. The purpose of this process is to optimize the composition of the elements in the melt as well as to homogenize the temperature in the liquid. It is common practice to model this process using smaller water models. LÄS MER
3. High resolution modelling and analysis of urban flooding
Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresursläraSammanfattning : The predictions on climate change and precipitation patterns in the near future, as well as urbanization, lead to higher volumes of runoff, which in turn challenge the sustainability and functionality of urban drainage pipe networks. In order to understand how these changes will affect the existing infrastructure in urban areas, integrated urban water model software are needed to identify effective solutions to minimize urban flooding.

4. What If We Tilt the AOD? : Developing a numerical and physical model of a downscaled AOD converter to investigate flow behaviour when applying an inclination.
Master-uppsats, KTH/MaterialvetenskapSammanfattning : In a scrap based stainless steel plant the dominant process for carbon reduction is the Argon oxygen decarburisation process (AOD). The process goes through three steps: decarburisation, reduction and desulphurisation where the main challenge is to oxidise carbon to CO without oxidising the expensive chromium. LÄS MER
5. Integrated Development for Sustainable Development : A study of the agriculture sector in Ghana
Master-uppsats, KTH/EnergisystemanalysSammanfattning : The growing demand for our most valuable resources; land, energy, and water, due to population growth and increased living standards, put the security of these resources at risk. The complexity of climate change, with the interdependencies between the aforementioned resources and potential feedback loops, makes the issue even more inextricable. LÄS MER
