2. 21. Computational studies of flow in Couette Rheometer and particle interaction in non-Newtonian fluids

   Author : Naser Hamedi; Strömningsteknik; []
   Keywords : Non-Newtonian fluids; Correction factor; Fluid properties; Couette Rheometer; Particle interaction; Sedimentation; Computational Fluid dynamics; Plug flow; Herschel Bulkley; Power-law fluid; Immeresed boundary method;

   Abstract : This work aims to study the flow of non-Newtonian fluids and has two main goals. First, the power-law and Herschel Bulkley fluids are studied in a Couette rheometer. Second, the static and dynamic interaction of dual particles in power-law fluid are investigated. READ MORE

4. 22. Fluid dynamics and flow structures of wood fibres suspended in gas flows

   Author : Olof Melander; Chalmers University of Technology; []
   Keywords : two-fluid model; fibres; flocculation; multiphase flow; flow regimes; particle transport; fibre suspensions; Particle Image Velocimetry; Computational Fluid Dynamics; lift force; concentration measurement;

   Abstract : The flow of wood fibres suspended in gas plays a major role in the MDF (Medium Density Fibreboard) production process. Development of machinery in this industry has traditionally been based on experience. Only recently has the use of numerical methods such as CFD (Computational Fluid Dynamics) become an important part of the development process. READ MORE

5. 23. Producer Gas Implementation in Steel Reheating Furnaces from Lab to Industrial Scale : A Computational Fluid Dynamics and Thermodynamics Approach

   Author : Mohsen Saffari Pour; Pär Göran Jönsson; Henrik Saxen; KTH; []
   Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk materialvetenskap; Materials Science and Engineering;

   Abstract : The integrated steel-making plants in Sweden contributed with approximately 8 % of the total CO2 emissions in the country in 2011. A major contributor to these emissions is the combustion of fossil fuels in different process units. Therefore, it is essential to reduce emissions by limiting the fossil fuels consumption in the steel industry. READ MORE

6. 24. Dynamics of Fluid Particles in Turbulent Flows; CFD simulations, Model Development and Phenomenological Studies

   Author : Ronnie Andersson; Chalmers University of Technology; []
   Keywords : Particle Image Velocimetry; Coalescence; Breakup; Multiphase Flow; Computational Fluid Dynamics; Planar laser induced fluorescence; Population Balance Modelling; Turbulence; High speed imaging technique; Mass Transfer; Refractive index matching;

   Abstract : The thesis investigates the dynamics of fluid particles in turbulent flows, which plays an important role in the chemical, pharmaceutical, food and petroleum industries. Phenomenological studies, new mathematical models for the breakup phenomena, and development of a simulation method for chemical reactors constitute the main parts of this thesis. READ MORE

7. 25. Towards Subject Specific Aortic Wall Shear Stress : a combined CFD and MRI approach

   Author : Johan Renner; Matts Karlsson; Toste Länne; Patrick Segers; Linköpings universitet; []
   Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fluid mechanics; Strömningsmekanik;

   Abstract : The cardiovascular system is an important part of the human body since it transports both energy and oxygen to all cells throughout the body. Diseases in this system are often dangerous and cardiovascular diseases are the number one killer in the western world. READ MORE
