2. 1. Mixing patterns in Rushton-turbine-agitated reactors

   Author : Fabrice Guillard; Livsmedelsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Food and drink technology; coherent mixing structure; geometrical analysis; dynamic structural analysis; conditional sampling; laser-induced fluorescence; mixing; stirred tank; Livsmedelsteknik;

   Abstract : This Ph.D. Thesis concerns the study of mixing in Rushton turbine agitated reactors. In industrial (bio)reactors, mixing is recognised as a limiting factor that significantly affects the performance of the process. READ MORE

4. 2. Some Fluid Dynamic Characteristics in the Scale-up of Rushton Turbine-Agitated Tanks

   Author : Eva Ståhl Wernersson; Livsmedelsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical technology and engineering; Livsmedelsteknik; Food and drink technology; Rushton turbine; turbulent kinetic energy; geometry; local energy dissipation rate; power input; scale-up; anemometry measurements; agitated tanks; turbulence; Kemiteknik och kemisk teknologi;

   Abstract : Turbine-agitated tanks are used in chemical and biochemical applications to increase mixing which, in turn, affects the yield, productivity and product quality. The purpose of this work was to study the hydrodynamic influence on the scale-up of turbine-agitated tanks, commonly used in fermentation. READ MORE

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

   Author : Ziyun Yu; KTH; []
   Keywords : hydrodynamics; stirred tank; phase Doppler anemometer;

   Abstract : 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. READ MORE

6. 4. The flow of pulp suspensions

   Author : Helena Fock; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Pulp suspensions; Velocity profile; Concentration profile; Wall layer; Particle image velocimetry; Flow behaviour; Computational fluid dynamics; Ultrasound velocity profiling;

   Abstract : Large quantities of pulp suspensions are handled in the pulp and paper industry and knowledge of their flow behaviour is very important in the design and operation of process equipment. Despite this, there is still a lack of a fundamental understanding of the mechanisms of the pulp suspension flow. READ MORE
