  1. 6. Robust intersection of hexahedral meshes and triangle meshes with applications in finite volume methods

    Författare :Frida Svelander; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; triangle-hex intersection; overlapping triangles; degenerate mesh; volume fraction; area fraction; cut cell; conjugated heat transfer.; triangle-hex intersection;

    Sammanfattning : The topic of this thesis is the intersection of a structured hexahedral grid and one or more triangle meshes. The interest in the problem has arisen in connection with a finite volume method for simulation of conjugated heat transfer. LÄS MER

  3. 7. Control of Wear-Resistance Properties in Ti-added Hypereutectic High Chromium Cast Iron

    Författare :Qiang Liu; Pär Jönsson; Keiji Nakajima; José Tinoco; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; High Chromium Cast Iron; cooling rate; Ti addition; M7C3; TiC; carbides size distributions; volume fraction; heat treatment; microstructure; mechanical properties; wear resistance;

    Sammanfattning : High chromium cast iron (HCCI) is considered as one of the most useful wear resistance materials and their usage are widely spread in industry. The wear resistance and mechanical properties of HCCI mainly depend on type, size, number, morphology of hard carbides and the matrix structure (γ or α). LÄS MER

    Sammanfattning : High chromium cast iron (HCCI) is considered as one of the most useful wear resistance materials and their usage are widely spread in industry. The mechanical properties of HCCI mainly depend on type, size, number, morphology of hard carbides and the matrix structure (γ or α). LÄS MER

  5. 9. Biomass and stem volume estimates for valuable timber species in Mozambique

    Författare :Rosta Mate; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Accurate aboveground biomass and stem volume estimates are crucial for the management of Mozambique's forests. This study focused on the development of aboveground biomass and stem volume equations for the three most valuable commercial timber species in Mozambique, Afzelia quanzensis Welm. (Chanfuta), Milletia stuhlmannii Taub. LÄS MER

    Författare :Henrik Bladh; Förbränningsfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Laser-Induced Incandescence; Laser Diagnostics; LII; Soot; Model; Engine; Particulates; Soot volume fraction; Combustion; Physics; Fysik; quantum mechanics; classical mechanics; Mathematical and general theoretical physics; Matematisk och allmän teoretisk fysik; thermodynamics; statistical physics; gravitation; relativity; kvantmekanik; klassisk mekanik; termodynamik; statistisk fysik; relativitet; Gases; Gaser; fluid dynamics; plasmas; Teknik; Laserteknik; Motors and propulsion systems; Motorer; framdrivningssystem; fluiddynamik; plasma; Technological sciences; Laser technology;

    Sammanfattning : The laser-induced incandescence technique (LII) is a laser-based diagnostic technique for measurements of soot volume fraction and particle size. The technique relies on detection of incandescent light from soot particles heated to around 4000 K using nanosecond laser pulses. LÄS MER
