  2. 21. Parallel computing of fluid flow through porous media

    Author : Gunnar Hellström; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Abstract : Fluid flow through porous media takes place in a variety of technical areas including ground water flow, flow through embankment dams, paper making, composites manufacturing, filtering, drying and sintering of iron ore pellets. When modelling these kinds of flows it is common practice to use averaging techniques rather than computing the detailed flow field in every single pore. READ MORE

  4. 22. Modelling the aerodynamics of iron ore pelletizing kilns

    Author : Reine Granström; Christian Fredriksson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Abstract : In an iron ore pelletizing plant, crude ore is upgraded to pellets to be used as feedstock in steel-making plants. As part of a grate-kiln pelletizing plant, the rotary kiln is an indurating furnace in which the pellets are sintered. READ MORE

  5. 23. Compression Moulding of SMC, Visualisation and Inverse Modelling

    Author : Torbjörn Odenberger; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Abstract : Before presenting the Sheet Moulding Compound (SMC) process, which is the primarily focus of this work, a literature survey is carried out to deal with fibre reinforced polymer composites in general. Then the first part of this work is presented and is primarily focused on experimental visualisation of the flow during mould closure of SMC. READ MORE

  6. 24. On the control of virtual violins : Physical modelling and control of bowed string instruments

    Author : Matthias Demoucron; Anders Askenfelt; Rene Causse; Benoit Fabre; Marcelo Wanderley; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bowed string; physical modelling; sound synthesis; performance control; violin playing; Corde frottée; modélisation physique; synthèse sonore; contrôle gestuel; violon; Struken sträng; fysikalisk modellering; ljudsyntes; musikutförande; violinspel; Other physics; Övrig fysik; Computer science; Datavetenskap; Acoustics; Akustik;

    Abstract :   This thesis treats the control of sound synthesis of bowed string instruments based on physical modelling. The work followed two approaches: (a) a systematic exploration of the influence of control parameters (bow force, bow velocity, and bow-bridge distance) on the output of a physical model of the violin, and (b) measurements and analyses of the bowing parameters in real violin playing in order to model and parameterize basic classes of bowing patterns for synthesis control.

  7. 25. Towards 3D modelling of Compression Moulding of SMC

    Author : Gustaf Alnersson; Staffan Lundström; Anna-Lena Ljung; Rickard Östlund; Yvonne Aitomäki; Malin Åkermo; Patrik Fernberg; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Abstract : The automotive industry is facing ever increasing demands for reduced emissions, and lightweight solutions are thusly required. One field that has significant potential in this regard is composite materials, which can offer a good combination of weight reduction and mechanical properties. READ MORE
