1. 11. Simulation of individual cells in flow

   Författare :Lailai Zhu; Luca Brandt; Michael Graham; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydrodynamic interaction; swimming microorganisms; capsule; Stokes flow; finite element method; boundary integral method; general geometry Ewald method; spectral element method; viscoelastic fluid; cellular deformation; flow cytometry; cell sorting; microrheology; Teknisk mekanik; Engineering Mechanics;

   Sammanfattning : In this thesis, simulations are performed to study the motion ofindividual cells in flow, focusing on the hydrodynamics of actively swimming cells likethe self-propelling microorganisms, and of passively advected objects like the red bloodcells. In particular, we develop numerical tools to address the locomotion ofmicroswimmers in viscoelastic fluids and complex geometries, as well as the motion ofdeformable capsules in micro-fluidic flows.

3. 12. Experimental Heat Transfer, pressure drop, and Flow Visualization of R-134a in Vertical Mini/Micro Tubes

   Författare :Wahib Owhaib; Björn Palm; Tassos Karayiannis; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Minichannel; microchannel; heat transfer; pressure drop; single-phase; two-phase; flow boiling; flow visualization; dry out; bubble behavior; flow pattern.; Mechanical energy engineering; Mekanisk energiteknik;

   Sammanfattning : For the application of minichannel heat exchangers, it is necessary to have accurate design tools for predicting heat transfer and pressure drop. Until recently, this type of heat exchangers was not well studied, and in the scientific literature there were large discrepancies between results reported by different investigators. LÄS MER

4. 13. Flow and Friction : On the Tactical Potential of Interfacing with Glitch Art

   Författare :Vendela Grundell; Anna Dahlgren; Mårten Snickare; Max Liljefors; Stockholms universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; Glitch; Contemporary Art; Photography; Digital Media; Interface; Internet; Systems Aesthetics; Network Society; Tactics; Phenomenology; Spectatorship; Viewer; Experience; Rosa Menkman; Phillip Stearns; Evan Meaney; konstvetenskap; Art History;

   Sammanfattning : This thesis aims to analyze how interfacing affects viewer experiences and viewer positions, and how glitch art online makes that effect visible. Glitch art is concerned with disruptions in the systems that govern how for instance photography is produced, circulated and displayed in a digital image flow. LÄS MER

5. 14. Advancements in stratified flows through simulation, experiment and open research software development

   Författare :Ashwin Vishnu Mohanan; Erik Lindborg; Pierre Augier; James J. Riley; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; geophysical flows; shallow water wave turbulence; energy cascade; stratified turbulence; waves and vortices; open source software; geofysikaliska strömningar; vågturbulens i grunt vatten; energi- kaskad; stratifierad turbulens; vågor och virvlar; öppen mjukvara; Engineering Mechanics; Teknisk mekanik;

   Sammanfattning : Two studies of two-dimensional models of flows influenced by stratification and stratification/rotation are carried out in order to investigate whether a two-dimensional model can reproduce a downscale energy cascade with an associated k − 5/3 wavenumber spectrum. Firstly, a series of highly resolved numerical simulations of the classical shallow water model is carried out. LÄS MER

7. 15. Nitrogen transformations in wetlands: Effects of water flow patterns

   Författare :Torbjörn Davidsson; Biologiska institutionen; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Hydrobiology; hydrology; infiltration; subsurface flow; surface flow; wetland; nitrogen; Denitrification; mineralization; nitrification; marine biology; aquatic ecology; limnology; Marinbiologi; limnologi; akvatisk ekologi;

   Sammanfattning : In this thesis, I have studied nitrogen turnover processes in watermeadows. A watermeadow is a wetland where water infiltrates through the soil of a grassland field. LÄS MER
