  2. 21. Laser beam-material interaction in Powder Bed Fusion

    Author : Tatiana Fedina; Knut Partes; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Produktionsutveckling; Manufacturing Systems Engineering;

    Abstract : The acceptance of additive manufacturing (AM) depends on the quality of final parts and the process repeatability. Recently, many studies have been dedicated to the establishment of the relationship between the process behavior and material performance. READ MORE

  4. 22. Fluid and suspension hydrodynamics in the impeller discharge flow of stirred tanks

    Author : Ziyun Yu; KTH; []
    Keywords : hydrodynamics; stirred tank; phase Doppler anemometer;

    Abstract : The hydrodynamics of an agitated tank have been studied byphase-Doppler anemometry. The focus is on the impeller anddischarge region of a 45o pitched blade turbine (PBT). Thestudy includes agitation of pure water as well as of a dilutesuspension of process particles. READ MORE

  5. 23. Lidar Studies of Tropospheric Aerosols and Clouds

    Author : K. Frans G. Olofson; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : An improved description of aerosol and cloud processes is a prerequisite for successful prediction of future climate change. The climate on Earth is controlled by the radiation budget, i.e. the relation between the radiation going into and out from the atmosphere. READ MORE

  7. 25. Entrained flow gasification of biomass : On atomisation, transport processes and gasification reactions

    Author : Mikael Risberg; Kevin Whitty; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

    Abstract : Since the energy consumption in the world is increasing together with an increase of greenhouse gas emission it is of importance to find alternatives to fossil fuels. Biomass is one of the alternative energy sources which is both renewable and CO2 neutral. READ MORE
