    Författare :Zhilei Wu; Strömningsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal engineering; Teknik; Technological sciences; Eulerian Lagrangian model.; Eulerian Eulerian model; Lagrangian Particle Tracking; Large Eddy Simulation; Two-phase flow; Particle Image Velocimetry; applied thermodynamics; Termisk teknik; termodynamik;

    Sammanfattning : This thesis considers the numerical study of dispersed two-phase flows.Numerical simulations have been done to investigate the particle trasportation/dispersion effect in turbulent two-phase flows. Both turbulent bubble/water flows and turbulent particle/air flows are studied. LÄS MER

  4. 3. Modelling of Moving Contact Lines in Two-Phase Flows

    Författare :Hanna Holmgren; Gunilla Kreiss; Stefan Turek; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computational fluid dynamics; Two-phase flow; Contact lines; Scientific Computing; Beräkningsvetenskap;

    Sammanfattning : Moving contact line problems appear in many natural and industrial processes. A contact line is formed where the interface between two immiscible fluids meets a solid wall. Examples from everyday life include raindrops falling on a window and water bugs resting on water surfaces. LÄS MER
