  1. 11. Distributed System Simulation Methods : For Model-Based Product Development

    Författare :Robert Braun; Petter Krus; Nigel Johnston; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Distributed system simulation can increase performance, re-usability and modularity in model-based product development. This thesis investigates four aspects of distributed simulation: multi-threaded simulations, simulation tool coupling, distributed equation solvers and parallel optimization algorithms. LÄS MER

  3. 12. Simulation of deformable objects transported in fluid flow

    Författare :Arash Alizad Banaei; Luca Brandt; Markus Holzner; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering Mechanics; Teknisk mekanik;

    Sammanfattning : Deformable particles suspended in a viscous fluid can be found in many industrial and biological applications. In this thesis, two different numerical tools have been developed to simulate suspensions of capsules, thin membranes enclosing a second fluid and a rigid nucleus so to work as model for ”Eukaryotic” cells, and flexible slender bodies known as filaments/fibres.

  5. 14. Large Eddy Simulation of an Oscillating Cylinder

    Författare :Andreas Feymark; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; numerical simulation; hydrodynamics; LES; subgrid modeling; forced oscillation;

    Sammanfattning : In this thesis Large Eddy Simulation of an Oscillating Cylinder is carried out studying the governing flow physics and modeling aspects such as effect of grid resolution and subgrid model. This also involves validation of the predictions with experimental data in terms of Fourier analysis, magnitude and characteristic shape of drag and lift force profiles. LÄS MER

  7. 15. Modelling Cavitation Mechanisms Using Large Eddy Simulation

    Författare :Nai Xian Lu; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hydrodynamics; Cavitation; cavitation erosion; cavitation mechanisms; numerical simulation; LES;

    Sammanfattning : Cavitation often brings negative effects such as performance degradation, noise and vibration, and material damage, being one of the limiting factors when designing propulsion systems. On the other hand, cavitation must be endured for an efficiently propelled system. LÄS MER
