  1. 1. Fluid flow through and deformation of wood fiber networks

    Författare :Patrik Pettersson; Veronique Michaud; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Sammanfattning : Cellulose-based commercial items such as paper and laminated flooring are vital to the local economy of northern Sweden. These products are commonly manufactured in suspension where fluids such as water or air are drained through the fiber network in some value-added steps in the manufacturing process. LÄS MER

  3. 2. Numerical Simulations of Turbulent Flows at Widely Different Mach Numbers

    Författare :Dragos Moroianu; Strömningsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vibration and acoustic engineering; Maskinteknik; hydraulics; vacuum technology; Mechanical engineering; plasma; Energy research; Energiforskning; fluiddynamik; plasmas; Gaser; fluid dynamics; Gases; computational fluid dynamics; Acoustic; hydraulik; vakuumteknik; vibrationer; akustik; compressible flow;

    Sammanfattning : The present thesis mainly focuses on the numerical simulation of the turbulent flow field and acoustics developed in different industrial applications. The study covers a large range of Mach numbers, starting from incompressible regimes and ending with a fully compressible flow. LÄS MER

  4. 3. Super-grid Linear Eddy Model (SG-LEM): Efficient mode- and regime-independent combustion closure for Large Eddy Simulation (LES)

    Författare :Abhilash Murlidharan Menon; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Large Eddy Simulation; Mapping-closure; Lagrangian splicing; Mesh coarse-graining.; Linear Eddy Model;

    Sammanfattning : Next-generation combustion technology such as ‘lean burn’ and HCCI (Homogeneous Charge Compression Ignition) present new challenges for  combustion modelling. The presence of locally varying combustion modes (premixed vs. non-premixed) and regimes (fast/non-fast chemistry vs. LÄS MER

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

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

    Sammanfattning : 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. LÄS MER

  7. 5. Experiments and numerical modelling of the SMC and autoclave processes

    Författare :Jimmy Kluge; Andy George; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Sammanfattning : The work presented in this thesis focus on the flow taking place in two industrialmanufacturing methods for composite manufacturing. The first method underinvestigation is compression moulding of Sheet Moulding Compound (SMC). LÄS MER
