  1. 1. Lagrangian Particles in Turbulence and Complex Geometries

    Author : Azad Noorani; Philipp Schlatter; Johan Revstedt; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Direct numerical simulation; wall turbulence; secondary motion; Teknisk mekanik; Engineering Mechanics;

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

  2. 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 : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; 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

  3. 3. Lagrangian CFD Modeling of Impinging Diesel Sprays for DI HCCI

    Author : Per Strålin; Hans-Erik Ångström; Christian Kreuger; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; HCCI; Diesel; early direct-injection; impinging nozzle; CFD; Lagrangian modeling; collision models; O’Rourke; Engineering mechanics; Teknisk mekanik;

    Abstract : The homogeneous charge compression ignition (HCCI) concept has been acknowledged as a potential combustion concept for engines, due to low NOx and soot emissions and high efficiency, especially at part-load. Early direct-injection (DI) during the compression stroke is an option when Diesel fuel is used in HCCI. READ MORE

  4. 4. Numerical Study of Dispersed Two-phase Flows

    Author : Zhilei Wu; Strömningsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 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

  5. 5. Numerical Modelling and Analysis of Orthogonal Metal Cutting

    Author : Mathias Agmell; Industriell Produktion; []
