  2. 1. Acoustic separation of submicron particles in gaseous flows

    Author : Ramin Imani Jajarmi; Laszlo Fuchs; Etienne Robert; Klas Engvall; Martin Wiklund; KTH; []
    Keywords : Acoustic; submicron particles; gaseous flows; separation; Engineering Mechanics; Teknisk mekanik;

    Abstract : The separation of submicron particles suspended in gaseous flows is a problem of great importance and is the subject of sustained research efforts. This is motivated by several challenges presented by modern science and technology requiring high separation efficiencies for submicron particles.

  4. 2. Continuous Ethanol Production from Dilute-acid Hydrolyzates: Detoxification and Fermentation Strategy

    Author : Ronny Purwadi; Högskolan i Borås; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HMF; serial bioreactor; immobilization; overliming; furfural; ethanol; continuous cultivation; S. cerevisiae; flocculating yeast; continuous detoxification; dilute-acid hydrolyzate;

    Abstract : The production of fuel ethanol from cellulosic biomass is of growing interest around the world. Lignocellulosic residuals can be used to produce transportation fuel, with the overall process having little net production of greenhouse gases. READ MORE

  5. 3. Separation of biomolecules using Open-Loop Non-Isocratic Simulated moving bed (SMB) technology

    Author : Deepti Sahoo; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Open-loop Non-Isocratic SMB; Simulated moving bed; True moving bed Chromatography; continuous separation; protein purification; batch chromatography;

    Abstract : In biotechnological industries, downstream processing is a bottleneck in the complete production process. There is a wish to reduce the costs and therefore one tries to operate separation technology in continuous mode. READ MORE

  6. 4. Numerical Modelling of Self-Compacting Concrete Flow : Discrete and Continuous Approach

    Author : Annika Gram; Johan Silfwerbrand; Ali Farhang; Mette R. Geiker; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SCC; rheology; Simulation of Flow; Simulering; Flöde; Självkompakterande Betong; Reologi; Construction materials; Konstruktionsmaterial;

    Abstract : With the advent of Self-Compacting Concrete (SCC) that flows freely, under the soleinfluence of gravity, the wish for hassle-free and predictable castings even in complexcases, spurged the simulation of concrete flow as a means to model and predictconcrete workability. To achieve complete and reliable form filling with smoothsurfaces of the concrete, the reinforced formwork geometry must be compatible withthe rheology of the fresh SCC. READ MORE

  7. 5. Modelling phase separation in Fe-Cr alloys : A continuum approach

    Author : Thomas Barkar; John Ågren; Nele Moelans; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Phase separation; spinodal decomposition; nucleation; diffusion; thermodynamics; kinetics; steel; ferritic;

    Abstract : The formation of Cr-rich and Fe-rich domains upon ageing of an initially homogeneous Fe-Cr alloy at elevated temperatures (300-600 ºC) is commonly referred to as phase separation. The behaviour originates from a miscibility gap in the Fe-Cr phase diagram. READ MORE
