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. 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

6. 4. Experimental Study and Modelling of Spacer Grid Influence on Flow in Nuclear Fuel Assemblies

   Author : Diana Caraghiaur Garrido; Henryk Anglart; Dominique Bestion; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; spacer grid influence; annular flow; deposition; Lagrangian Particle Tracking;

   Abstract : The work is focused on experimental study and modelling of spacer grid influence on single- and two-phase flow. In the experimental study a mock-up of a realistic fuel bundle with five spacer grids of thin plate spring construction was investigated. A special pressure measuring technique was used to measure pressure distribution inside the spacer. 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
