  2. 6. Motion of Metallic Particles in Gas Insulated Systems

    Author : Magnus Holmberg; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The motion of a charged metallic particle subjected to an electric field in a gas insulated system is controlled by several parameters. The higher applied electric field, the better the individual parameters have to be mod eled in order to make satisfactory calculations of the motion. READ MORE

  4. 7. Eulerian-Lagrangian modeling of particle motion in exhaust gas aftertreatment systems

    Author : Henrik Ström; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; urea-SCR; particle trapping; flow-through filter; urea decomposition; diesel particulate matter; particle motion; particle filter; AdBlue-spray; Eulerian-Lagrangian modeling;

    Abstract : In the work to design and optimize new aftertreatment system devices for NOx reduction and particulate matter removal in lean engine exhaust (such as diesel exhaust), it is of great help to be able to perform quick, robust and reliable computer simulations of system performance. A suitable platform for such simulations is Computational Fluid Dynamics (CFD) software. READ MORE

  5. 8. Non-Spherical Particle Interaction in Duct and Jet Flow

    Author : Ammar Hazim; Matthias Mandø; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solid-gas flow; turbulence modulation; duct flow; coaxial jets flow; swirl jet flow; active flow control; synthetics jet; biomass powder; non-spherical particles; PIV measurement; Strömningslära; Fluid Mechanics;

    Abstract : Wood waste is the most popular biomass recourse for many nations. Burned wood can, direct or indirect, release one of the greenhouse gases, carbon dioxide. The process can still be seen as a renewable source of energy since replanting of the trees and crops are consuming nearly the same amount of carbon dioxide through photosynthesis. READ MORE

  6. 9. Fluid Dynamics in Gas-Liquid Stirred Tank Reactors: Experimental and Theoretical Studies of Bubble Coalescence

    Author : Rahman Sudiyo; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Computational Fluid Dynamics; Turbulence; Buoyancy; Bubble Coalescence; Multiphase Flow; High-Speed Video Imaging; Particle Image Velocimetry; Collision Mechanisms;

    Abstract : This work deals with studies of bubble coalescence in turbulent flows of gas-liquid stirred tank reactors. Coalescence plays an important role in determining bubble size distribution, on which flow and mass transfer in such reactors largely depend. READ MORE

  7. 10. Numerical study of dynamics of mass-emitting particles in multi-phase flow

    Author : Zeinab Moradi Nour; Minh Do-Quang; Fredrik Lundell; Gustav Amberg; Hans Kuipers; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; particles with outflow; lattice Boltzmann method; particle interaction; liquid-gas-solid systems; sedimentation; shear flow; Engineering Mechanics; Teknisk mekanik;

    Abstract : Suspended particles can be found in wide range of industrial applications such as food industry, mining industry and energy conversion processes. Depending on flow cases which particles are involved, different dynamics and motions are expected from suspended particles. READ MORE
