  1. 1. Search for efficient time integration methods in structural dynamics for finite element meshes with large variations of properties

    Författare :Annika Moström; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Sammanfattning : Direct time integration methods are the most commonly used solution algorithms for analysis of non-linear transient phenomena in finite element computations. One major disadvantage with these methods is that stability and accuracy of the computation are governed by the smallest element in the mesh assuming all other properties constant. LÄS MER

  3. 2. Modelling and simulation of building components : thermal interaction between multilayer wall and hydronic radiator

    Författare :Christian Brembilla; Thomas Olofsson; Per Sahlin; Persson Leif; Annika Moström; Umeå universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydronic radiator; multilayer wall; efficiencies of emission; systemanalys; Systems Analysis; engineering science with specialization in microsystems technology; teknisk fysik med inriktningen mikrosystemteknik;

    Sammanfattning : Background and Scope: The scope of this thesis is to investigate the thermal behaviour of building components as hydronic radiator and multilayer walls subjected to dynamic conditions. The modelling and simulation of these building components provide information on how these components thermally interact among each other. LÄS MER
