1. 1. Heat Transfer and Hydrodynamics in Falling Film Evaporation of Black Liquor

   Författare :Miriam Johansson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; correlation; black liquor; turbulence; hydrodynamics; kraft pulp mill; falling film; Heat transfer; evaporation; experimental; evaporator;

   Sammanfattning : The evaporation plant is one of the major steam consumers in kraft pulp mills, which are the dominant type of chemical pulp mill in Sweden. Previous studies have shown potential to decrease the live steam demand for the pulp process, e.g. LÄS MER

3. 2. Hydrodynamics considerations in cells systems from ocean flow to perfusion cultivation process

   Författare :Caijuan Zhan; Véronique Chotteau; Jeffrey Chalmers; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Microorganism; cells; hydrodynamics; turbulence; numerical simulation; CFD; Resonance; Wave bioreactor; ATF; TFF; perfusion; design feeding strategy; Bioteknologi; Biotechnology;

   Sammanfattning : Microorganisms and animal cells are grown surrounded by fluid, which is providing them with nutrients and removing their waste products. In nature and industry processes, cells/microbes can be subject to aggressive environments, such as turbulent flow or shear flow. LÄS MER

4. 3. Fluid and suspension hydrodynamics in the impeller discharge flow of stirred tanks

   Författare :Ziyun Yu; KTH; []
   Nyckelord :hydrodynamics; stirred tank; phase Doppler anemometer;

   Sammanfattning : The hydrodynamics of an agitated tank have been studied byphase-Doppler anemometry. The focus is on the impeller anddischarge region of a 45o pitched blade turbine (PBT). Thestudy includes agitation of pure water as well as of a dilutesuspension of process particles. LÄS MER

7. 5. Hydrodynamics of Binary Bose-Einstein Condensates and Hydro-elasticity of the Inner Crust of Neutron Stars

   Författare :Dmitry Kobyakov; Emil Lundh; Vitaly Bychkov; Mattias Marklund; Achim Schwenk; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Binary Bose-Einstein condensates in ultracold gases; hydrodynamics; quantum turbulence; neutron stars; the inner crust; nuclear astrophysics; fysik; Physics;

   Sammanfattning : In the present thesis, “Hydrodynamics of Binary Bose-Einstein Condensates and Hydro-elasticity of the Inner Crust of Neutron Stars”, the hydrodynamic effects, instabilities and superfluid turbulence in binary immiscible ultracold gases, and hydro-elastic macroscopic coupled modes and microscopic structure of the inner layers of the crust of neutron stars, are studied. The ultracold gas dynamics can be realized in the laboratory. LÄS MER
