2. 1. Fluid Management in Haemodialysis : Studies on current practices and new methods

   Author : Jenny Stenberg; Hans Furuland; Magnus Lindberg; Eva Tiensuu Janson; Bernd Stegmayr; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Haemodialysis; Fluid management; Fluid overload; Bioimpedance spectroscopy; Dry weight; Brain natriuretic peptide; Decision aid; Medicinsk vetenskap; Medical Science;

   Abstract : Chronic fluid overload has been identified as an independent predictor of mortality in haemodialysis patients, and 30% remain fluid overloaded at dry weight. The use of bioimpedance spectroscopy (BIS) in fluid management may improve blood pressure control and cardiovascular status. READ MORE

4. 2. Turbulent flows over permissive boundaries and porous walls

   Author : Seyed Morteza Habibi Khorasani; Shervin Bagheri; Geert Brethouwer; Alfredo Soldati; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Direct numerical simulations; wall-bounded turbulence; flow control; porous walls; heat transfer; Direkta numeriska simuleringar; väggbunden turbulens; flödeskontroll; porösa väggar; värmeöverföring; Teknisk mekanik; Engineering Mechanics;

   Abstract : This thesis investigates how in wall-bounded turbulent flows changes to the wall can induce changes in the flow. To this end, we investigate the use of wall boundary conditions meant to mimic the effect of textured surfaces. READ MORE

5. 3. Modelling flow with free and rough surfaces in the vicinity of hydropower plants

   Author : Anders G. Andersson; Nils Rüther; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

   Abstract : Flow with free and rough surfaces near hydropower stations is of interest for both engineering and environmental applications. Here, Computational Fluid Dynamics simulations of free surface flow and flow over rough surfaces in regulated rivers were performed in applications such fish migration, spillway design and flow over rough surfaces as in hydropower tunnels or natural channels.

6. 4. A Novel Immersed-Boundary Method for Multiple Moving and Interacting Bodies

   Author : Andreas Mark; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fluid-structure interaction; DNS; immersed-boundary method;

   Abstract : This thesis describes the development, implementation and validation of an implicit, second order accurate, finite-volume and instationary immersed-boundary method for simulating the detailed flow around multiple arbitrary moving and interacting bodies. The potential for flows including moving bodies or boundaries, such as multiphase flows still has to be fully realized. READ MORE

7. 5. Using Energy Fluxes to Analyze the Hydrodynamic Performance of Marine Propulsion Systems

   Author : Jennie Andersson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Propulsor-Hull interaction; Control volume analysis; RANS; Energy balance analysis; CFD;

   Abstract : The strive towards more fuel efficient ships is a continuously ongoing process, motivated by both economic and regulatory reasons. An important aspects to consider for the final fuel consumption is the propulsion system performance in relevant operating conditions. READ MORE
