  2. 1. Numerical Study of Dispersed Two-phase Flows

    Author : Zhilei Wu; Strömningsteknik; []
    Keywords : 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;

    Abstract : 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. READ MORE

  4. 2. On the Agglomeration of Particles in Exhaust Gases

    Author : Ghulam Majal; Mihai Mihaescu; Mats Åbom; Mikael Karlsson; Lisa Prahl Wittberg; Henrik Ström; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Multiphase flow; DES; particulate matter; exhaust after treatment; particle agglomeration; Lagrangian particle tracking; Teknisk mekanik; Engineering Mechanics;

    Abstract : Particulate emissions from road transportation are known to have an adverse impact on human health as well the environment. As the effects become more palpable, stricter legislation have been proposed by regulating bodies. READ MORE

  5. 3. Particle-laden Turbulent Wall-bounded Flows in Moderately Complex Geometries

    Author : Azad Noorani; Philipp Schlatter; Helge Andersson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; turbulent; complex geometry; particle; Teknisk mekanik; Engineering Mechanics;

    Abstract : Wall-bounded turbulent dispersed multiphase flows occur in a variety of industrial, biological and environmental applications. The complex nature of the carrier and the particulate phase is elevated to a higher level when introducing geometrical complexities such as curved walls. READ MORE

  6. 4. Modeling of aerodynamic particle interaction

    Author : Asim Jadoon; Strömningsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The purpose of the current study is to investigate the effect of particle-pair interaction for various separation distances and angular positions. The results obtained are used in a particle-laden turbulent jet flows in order to improve the existing Lagrangian Particle Tracking (LPT) models. READ MORE

  7. 5. LES of Jets and Sprays Injected into Crossflow

    Author : Mirko Salewski; Strömningsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gaser; fluid dynamics; large eddy simulation; spray; plasmas; Gases; lagrangian particle tracking; jet in crossflow; fluiddynamik; plasma;

    Abstract : The objective of this thesis is to numerically simulate a fluid jet injected into a crossflow of the same or another fluid, respectively. Such flows are encountered in many engineering applications in which cooling or mixing plays an important role, e.g. gas turbine combustors. READ MORE
