1. 1. Fluid Dynamics in Stirred Vessels - Experiments and simulations of single-phase and liquid-liquid systems

   Författare :Fredrik Svensson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Particle Image Velocimetry PIV ; single-phase; Laser Doppler Anemometry LDA ; mixing; liquid-Liquid; immiscible; stirred tank; Rushton turbine; Computational Fluid Dynamics CFD ; macro-instability; frequency analysis; refraction index matched;

   Sammanfattning : This thesis applies experimental measurement techniques and computational fluid dynamics to evaluate turbulent mixing of liquid-liquid systems in stirred vessels. Also studies of macro-instabilities in a single-phase system and how they affect flow and thus mixing are conducted. LÄS MER

3. 2. Experimental studies of large particles in Newtonian and non-Newtonian fluids

   Författare :Sagar Zade; Luca Brandt; Fredrik Lundell; Ellen Longmire; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; turbulence; finite-size; particle-laden flows; duct flow; pipe flow; viscoelastic fluid; viscoplastic fluid; Engineering Mechanics; Teknisk mekanik;

   Sammanfattning : In everyday human life, laminar flow is arguably an exception whereas turbulent flow is the norm. Yet, the former has been much better understood, naturally since laminar flow renders itself to treatment in a relatively easier fashion compared to turbulence with its chaotic dynamics across multiple scales in space and time.
