  3. 2. Experimental and Mathematical Study of Incompressible Fluid Flow through Ceramic Foam Filters

    Författare :Shahin Akbarnejad; Ragnhild Elizabeth Aune; Pӓr Jönsson; Andreas Westermoen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Ceramic Foam Filters (CFFs) are widely used to filter solid particles and inclusions from molten metal in metal production, particularly in the aluminum industry. In general, the molten metal is poured on the top of a ceramic foam filter until it reaches a certain height, also known as metal head or gravity head. LÄS MER

  4. 3. Refractory corrosion in biomass gasification

    Författare :Markus Carlborg; Rainer Backman; Dan Boström; Ragnhild Aune; Umeå universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Refractory corrosion; slag; biomass; gasification; Materials Science; materialvetenskap;

    Sammanfattning : To stop the net emission of CO2 to the atmosphere, we need to reduce our dependency of fossil fuels. Although a switch to a bio-based feedstock hardly can replace the total amount of fossils used today, utilization of biomass does still have a role in a future in combination with other techniques.

  5. 4. Magnetic Fields and Induced Power in the Induction Heating of Aluminium Billets

    Författare :Mark William Kennedy; Ragnhild E. Aune; Andreas Westermoen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Induction; heating; billets; coils; magnetic fields;

    Sammanfattning : Induction heating is a common industrial process used for the reheating of billets before extrusion or forging. In this work the influence of the coil and work piece geometry, the effect of the electrical properties of the work piece, and the coil current and frequency, on the magnetic flux density and resulting work piece heating rates were studied.
