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. 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

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

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

   Abstract : 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. READ MORE

6. 4. The influence of inertia on the rotational dynamics of spheroidal particles suspended in shear flow

   Author : Tomas Rosén; Fredrik Lundell; Minh Do-Quang; Johan Revstedt; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fluid mechanics; dispersed particle flows; inertia; non-spherical particles; non-linear dynamics; Engineering Mechanics; Teknisk mekanik;

   Abstract : Dispersed particle flows occur in many industrial, biological and geophysical applications. The knowledge of how these flow behave can for example lead to improved material processes, better predictions of vascular diseases or more accurate climate models. READ MORE

7. 5. Numerical Modeling of Turbulent Gas-Particle Flow

   Author : Aldo Benavides; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; turbulence modulation.; kinetic theory; Eulerian-Eulerian model;

   Abstract : This work presents a theoretical and numerical study of gas-particle two-phase flow within the Eulerian framework. Although gas-particle flows have been extensively studied, there is still no general agreement on the constitutive equations for an Eulerian-Eulerian model in which the dispersed phase is treated as a continuum, i.e. a granular fluid.
