Dissertation
Oscillating grid turbulence and its influence on gas liquid mass transfer and mixing in non-Newtonian media
TL;DR: In this paper, the authors studied fundamental aspects of turbulent mass transfer at a flat interface between carbon dioxide and a non-Newtonian liquid, stirred by homogeneous and quasi isotropic turbulence.

Flow around an oscillating grid in water and shear-thinning polymer solution at low Reynolds number
Tom Lacassagne,Tom Lacassagne,Adrien Lyon,Serge Simoëns,Mahmoud El Hajem,Jean-Yves Champagne +5 more
TL;DR: In this paper, Lacassagne et al. studied the influence of shear-thinning property of dilute polymer solutions (DPS) on mean flow, oscillatory flows, and turbulence around an oscillating grid.

Multi-objective optimization for sensor placement: An integrated combinatorial approach with reduced order model and Gaussian process
TL;DR: In this paper, a sensor placement method that maximizes monitoring performance while minimizing deployment cost is proposed, which integrates a reduced order model and multi-objective combinatorial optimization, and a lazy greedy (LG)- ∊ -constraint optimization to derive the Pareto-optimal sensor configurations.

Journal ArticleDOI
The Proper Orthogonal Decomposition in the Analysis of Turbulent Flows
TL;DR: The Navier-Stokes equations are well-known to be a good model for turbulence as discussed by the authors, and the results of well over a century of increasingly sophisticated experiments are available at our disposal.
Journal ArticleDOI
The mechanics of an organized wave in turbulent shear flow. Part 3. Theoretical models and comparisons with experiments
TL;DR: In this paper, the dynamical equations governing small amplitude wave disturbances in turbulent shear flows are derived, which require additional equations or assumptions about the wave-induced fluctuations in the turbulence Reynolds stresses before a closed system can be obtained.
Journal ArticleDOI
An experimental study of the steady and unsteady flow characteristics of stirred reactors
TL;DR: In this article, a baffled stirred reactor vessel driven by a six-blade disk impeller was investigated using laser-slit photography, and the results showed an inclination of the impeller stream and the formation of ring vortices above and below, which depend on the clearance.

PIV study of small‐scale flow structure around a Rushton turbine
Kendra V. Sharp,Ronald J. Adrian +1 more
TL;DR: In this paper, the structure of turbulent motions was measured in a region surrounding the blade tips of a Rushton turbine mixer and the tip vortices responsible for micromixing were created in this region.

Experimental analysis of hydrodynamics in a radially agitated tank
Renaud Escudié,Alain Liné +1 more
TL;DR: In this article, a PIV technique is used to analyze the local hydrodynamics generated by a Rushton turbine, where different types of motion coexist in the tank: the mean flow, the periodic fluctuations induced by the blade rotation in the impeller region, and the turbulent fluctuations that dissipate the kinetic energy.
