  4. 8. Degenerating Orr-Sommerfeld eigenmodes and development of three-dimensional perturbations

    Författare :Rajaratnam Shanthini; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Sammanfattning : Degeneracies of temporally damped Orr-Sommerfeld eigenmodes are studied primarily for plane Poiseuille flow. The discrete spectrum of the eigenmodes is shown to possess infinitely many degeneracies, each appearing at a certain combination of k (the modulus of resultant wavenumber) and α R (the streamwise wavenumber times the Reynolds number).

  5. 9. Energy-momentum conserving time-stepping algorithms for nonlinear dynamics of planar and spatial Euler-Bernoulli/Timoshenko beams

    Författare :Sophy Chhang; Jean-Marc Battini; Mohammed Hjiaj; Reijo Kouhia; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nonlinear Dynamics; Energy-momentum conserving scheme; 2D co-rotational beam; Geometrically exact 3D Euler-Bernoulli beam; impact; Byggvetenskap; Civil and Architectural Engineering;

    Sammanfattning : Large deformations of flexible beams can be described using either the co-rotational approach or the total Lagrangian formalism. The co-rotational method is an attractive approach to derive highly nonlinear beam elements because it combines accuracy with numerical efficiency. LÄS MER
