  3. 2. Melt convection in welding and crystal growth

    Författare :Minh Do-Quang; Gustav Amberg; Andreas Ludwig; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering physics; thermocapillary convection; gas-tungsten arc welding; floating zone; parallel computing; finite element method; Teknisk fysik; Engineering physics; Teknisk fysik;

    Sammanfattning : A parallel finite element code with adaptive meshing was developed and used to study three dimensional, time-dependent fluid flows caused by thermocapillary convection as well as temperature and dopant distribution in fusion welding and floating zone crystal growth. A comprehensive numerical model of the three dimensional time-dependent fluid flows in a weld pool had been developed. LÄS MER

  4. 3. Phase change, surface tension and turbulence in real fluids

    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering Mechanics; Teknisk mekanik;

    Sammanfattning : Sprays are extensively used in industry, especially for fuels in internal combustion and gas turbine engines. An optimal fuel/air mixture prior to combustion is desired for these applications, leading to greater efficiency and minimal levels of emissions. LÄS MER

  5. 4. Numerical study of dynamics of mass-emitting particles in multi-phase flow

    Författare :Zeinab Moradi Nour; Minh Do-Quang; Fredrik Lundell; Gustav Amberg; Hans Kuipers; KTH; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  7. 5. Angular dynamics of non-spherical particles in linear flows related to production of biobased materials

    Författare :Tomas Rosén; Fredrik Lundell; Daniel Söderberg; Minh Do-Quang; Jason E. Butler; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fluid mechanics; dispersed particle flows; inertia; non-linear dynamics; rotary diffusion; characterization techniques;

    Sammanfattning : Dispersed particle flows are encountered in many biological, geophysical but also in industrial situations, e.g. during processing of materials. In these flows, the particles usually are non-spherical and their angular dynamics play a crucial role for the final material properties. LÄS MER
