  2. 1. SAWING STRATEGIES FOR TROPICAL HARDWOOD SPECIES : Simulation studies based on industrial conditions of Mozambique

    Author : Pedro Ah Shenga; Dick Sandberg; Olof Broman; Mats Nylinder; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sawing strategies; tropical hardwood species; simulation; volume yield; log grading; umbila; jambirre; Träteknik; Wood Science and Engineering;

    Abstract : The harvesting of Mozambique tropical hardwood species is considerable higher than the natural regrowth in the forest and the stock is decreasing drastically. Therefore, it is important to improve the material recovery when the wood is refined (i.e., in sawing and further refinement to products such as joineries, furniture etc. READ MORE

  4. 2. Mechanical processing for improved products made from Swedish hardwood

    Author : Jimmy Johansson; Dick Sandberg; František Hapla; Växjö universitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; capillarity; capillary transport; wood products; customer requirements; ecoeffectiveness; ; sawing pattern; star-sawing; the PrimWood Method; timber products; volume yield; water transport; Wood fibre and forest products; Träfiber- och virkeslära;

    Abstract : Swedish hardwood is today used in the energy, pulp and mechanical hardwood industries. Only very small volumes of Swedish hardwood are, however, consumed by the mechanical industry that normally pays the highest timber price. READ MORE

  5. 3. Finite Volume Methods on Quadrilateral and Moving Meshes

    Author : Fredrik Svensson; Matematik LTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; numerisk analys; system; kontroll; systems; control; numerical analysis; finite volume method; Datalogi; Computer science; moving mesh method; higher order reconstruction; hyperbolic conservation law;

    Abstract : The topic of this thesis is the study of finite volume methods for hyperbolic conservation laws on non-uniform meshes. A high-order hyperbolic reconstruction method is presented. The method is constructed for quadrilateral meshes, since more realistic hyperbolic problems involve more complicated problem domains than the standard rectangular ones. READ MORE

  6. 4. Methods for Reducing the Complexity of Geometrical Structures Based on CFD Programming : Time Efficient Simulations Based on Volume Forces Coupled with Single and Two-phase Flow

    Author : Kamal Rezk; Lars Nilsson; Jonas Berghel; Erik Dahlquist; Karlstads universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Numerical design cycle; CFD; porous media; volume forces; heat exchanger; vacuum dewatering; time efficient simulations; Miljö- och energisystem; Environmental and Energy Systems;

    Abstract : Throughout recent years, computer based programs have been applied to solve and analyse industrial problems encountered global fields such as automobile design for reduction of CO2-gas, designing wind parks aimed at increasing power output etc. One of these developed programs is Computational Fluid Dynamics (CFD) which numerically solves complex flow behaviour based on computer power.
