  1. 16. Effects of microbial community coalescence in lake water at ice break-off

    University essay from

    Author : Christoffer Melhus; [2019]
    Keywords : Freshwater lakes; ice break-off; microbial community coalescence; dissolved organic matter; microbial enzymatic activity; primary production; photo degradation.;

    Abstract : The period of ice break-off in spring is a key event for many biogeochemical processes in lakes globallly. The biogeochemical processes occurring at ice break-off have the potential of influencing characteristics of lakes throughout spring and summer, including algal blooms and greenhouse gas emission.

  3. 17. Numerical simulations of mixing for gas exhaust treatment

    University essay from KTH/Strömningsmekanik och Teknisk Akustik

    Author : Viktor Lahti; [2019]
    Keywords : ;

    Abstract : According to the World Health Organisation, nine out of ten people live in places with sub par air quality. Therefore, the study of the treatment of polluted air is from a global point of view of great importance, and a matter of life quality for both humans and as well as animals. READ MORE

  4. 18. Towards a prototype of a modular biogas system

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Arvid Emilsson; Andreas Buhrgard; [2019]
    Keywords : Biogas; Vehicle gas; CHP; micro-CHP; farm-based; energy audit; techno-economic analysis; energy evaluation; upgrading; water-scrubber; small-scale; scalable; stand-alone; mass-production;

    Abstract : As of today, large unused potential for biogas production exist within the Swedish agriculture sector. The biogas production within this sector is, however, associated with several problems such as poor energy efficiency and non-profitable systems. This is to some degree due to lack of standardized technical solutions. READ MORE

  5. 19. 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.

    University essay from KTH/Materialvetenskap

    Author : Serg Chanouian; [2019]
    Keywords : AOD; inclination angle; penetration depth; mixing time;

    Abstract : 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. READ MORE

  6. 20. Evaluation of CFD Methods for Prediction of Total Temperature and Total Pressure Distribution in Gas Turbines

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Lars Fredrik Wahlgren; [2019]
    Keywords : ;

    Abstract : This thesis work was performed as a collaboration between the Royal Institute of Technology in Stockholm and Siemens Industrial Turbomachinery in Finspång. It was undertaken with the purpose of investigating the use of CFD methods in ANSYS CFX to predict flow mixing in gas turbines. READ MORE
