  1. 1. Computational methods for microfluidics

    Författare :Ludvig af Klinteberg; Anna-Karin Tornberg; Peter Hansbo; KTH; []

    Sammanfattning : This thesis is concerned with computational methods for fluid flows on the microscale, also known as microfluidics. This is motivated by current research in biological physics and miniaturization technology, where there is a need to understand complex flows involving microscale structures. Numerical simulations are an important tool for doing this. LÄS MER

    Sammanfattning : As a result of the increase in accessibility of computational resources and the increase in the power of the computers during the last two decades, designers are able to create computer models to simulate the behavior of a complex products. To address global competitiveness, companies are forced to optimize their designs and products. LÄS MER

  3. 3. Cam Roller Contact : The topographical aspect

    Författare :Frédéric Cabanettes; Bengt Göran Rosén; Peter Hansbo; Högskolan i Halmstad; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; injection cam; roller; surface topography; rough contact model; wear test; classification of surfaces; manufacturing evaluation; Mechanical manufacturing engineering; Mekanisk tillverkningsteknik;

    Sammanfattning : The automotive industry and the design of engines are strongly ruled by performance and legislation demands. First order aspects defining the main functions of a component are well known and new challenges appear at a lower scale. LÄS MER

  4. 4. Optimal Control of Partial Differential Equations in Optimal Design

    Författare :Jesper Carlsson; Anders Szepessy; Peter Hansbo; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Optimal design; Numerical analysis; Numerisk analys;

    Sammanfattning : This thesis concerns the approximation of optimally controlled partial differential equations for inverse problems in optimal design. Important examples of such problems are optimal material design and parameter reconstruction. In optimal material design the goal is to construct a material that meets some optimality criterion, e.g. LÄS MER

  5. 5. Finite element methods for surface problems

    Författare :Mirza Cenanovic; Peter Hansbo; Kent Salomonsson; Paul Houston; Jönköping University; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; trace finite element method; membrane; mean curvature; level-set method;

    Sammanfattning : The purpose of this thesis is to further develop numerical methods for solving surface problems by utilizing tangential calculus and the trace finite element method. Direct computation on the surface is possible by the use of tangential calculus, in contrast to the classical approach of mapping 2D parametric surfaces to 3D surfaces by means of differential geometry operators.
