Ji, Ning (author)Emulsions, characterized as a metastable dispersion of one liquid into a second one in the presence of surface-active agents, have complex rheology that interests both physicists and industries. Depending on the volume fraction of the dispersed phase ($\phi$), emulsions can display both solid-like and liquid-like behavior. Rheometrical...master thesis 2023

Nadorp, Tim (author)Dense suspensions can be found in various industrial and natural processes. A relatively new technique uses the principle of additive manufacturing to produce products from a wide variety of materials by printing with dense suspensions. To reach a high print quality the suspension rheology must be understood very well. Current knowledge about...master thesis 2022

Veldhuizen, H.V. (author), van der Zwaag, S. (author), van der Veen, M.A. (author)Flow-induced disturbances were applied during the synthesis of a naphthalene diimide covalent organic framework (NDI-COF), which resulted in different COF polymer networks. We discovered that a high intensity of stirring resulted in more aggregated structures on both the micro- and nano-length scale. Subsequently, these structures absorbed...journal article 2022

Greidanus, A.J. (author)This thesis describes the investigation of the dynamics of turbulent shear flows over non-smooth surfaces. The research was conducted in two parts, related to the experimental facility used in combination with the applied functional surface. The first part describes the experiments of a turbulent Taylor-Couette flow over a...doctoral thesis 2020

Dash, A. (author), Anantharaman, Arjun (author), Poelma, C. (author)We extend upon the known flow transitions in neutrally buoyant particle-laden Taylor-Couette flows by accessing higher suspension Reynolds numbers in a geometry with radius ratio and aspect ratio. Flow transitions for several particle volume fractions () are investigated by means of flow visualization experiments, in a flow driven by a...journal article 2020

Tokgoz, S. (author), Elsinga, G.E. (author), Delfos, R. (author), Westerweel, J. (author)We report on the experimental investigation of the large-scale instantaneous flow structures in turbulent Taylor–Couette flow using tomographic particle image velocimetry. The results indicate three distinct regimes for counter-rotating flow within a shear Reynolds number range of 11000<ReS<47000 . Close to only inner cylinder rotation,...journal article 2020

Anantharaman, Arjun (author)Taylor-Couette (TC) flow refers to the flow in the annulus between two coaxial, independently rotating cylinders. The TC system has been subject to multiple experiments spanning over decades due to the instability phenomena that occur in the flow. When the rotation rates of the cylinders are increased beyond a critical value, instabilities...master thesis 2019

Thota Radhakrishnan, A.K. (author), van Lier, J.B. (author), Clemens, F.H.L.R. (author)Information on the rheology of domestic slurries is essential in designing pipeline transportation in novel sanitation systems. As concentrated slurries in their original collected state have wide particle size distribution, with particles up to 2 mm, a wide gap rheometer is used to acquire the rheograms. Rheograms obtained from a wide gap...journal article 2018

Gül, M. (author), Elsinga, G.E. (author), Westerweel, J. (author)This paper describes the hysteresis in the torque for Taylor–Couette flow in the turbulent flow regime for different shear Reynolds numbers, aspect ratios and boundary conditions. The hysteresis increases with decreasing shear Reynolds number and becomes more pronounced as the aspect ratio is increased from 22 to 88. Measurements conducted in...journal article 2018

Krintiras, G. (author)To meet the increasing need for protein-rich food of an ever growing population, plant-based proteins are being utilized in meat products as replacements for animal-based proteins. Legumes such as soy can serve as an alternative protein source, by featuring both high protein content (36%) and protein functionality (gelation). Nowadays various...doctoral thesis 2016

Alidai, A. (author), Greidanus, A.J. (author), Delfos, R. (author), Westerweel, J. (author)The transition from the laminar to the turbulent regime in linearly stable shear flows, for example, pipe and plane Couette flows, occurs abruptly with no precursor. The evolution of turbulent spots has been studied to better understand the dynamics of this transition and the onset of turbulence. These studies have mostly focused on pipe flows...journal article 2015

Salewski, M. (author), Eckhardt, B.E. (author)Shearing and rotational forces in fluids can significantly alter the transport of momentum. A numerical investigation was undertaken to study the role of these forces using plane Couette flow subject to rotation about an axis perpendicular to both wall-normal and streamwise directions. Using a set of progressively higher Reynolds numbers up to...journal article 2015

Tokgöz, S. (author)Taylor-Couette flow is defined as the flow confined between two coaxial cylinders which can rotate independently. Several different flow states can be observed in the gap between the cylinders by changing the rotation speeds and the rotating directions of the cylinders. The aim of this thesis is to investigate the previously reported change of...doctoral thesis 2014

Alidai, A. (author)The most recent studies of intermittent state in linearly stable shear flows, like pipe, Plane Couette and Taylor Couette flow, have shown that turbulent structures, created by finite-amplitude perturbation, have an exponential distribution of the lifetimes. Here we experimentally examine the lifetime of turbulent spot in Taylor Couette flow ...master thesis 2011

Hollerbach, R. (author)We consider the flow of an electrically conducting fluid between differentially rotating cylinders, in the presence of an externally imposed magnetic field. Several codes are presented to study this problem, consisting of linear eigenvalue and nonlinear time-stepping programs. Depending on whether the magnetic Reynolds number is small or large,...conference paper 2006

Fournier, A. (author)We present a Fourier-spectral element approximation of electromagnetic induction (and magnetohydrodynamics) in a domain bounded by a spherical interface. The electromagnetic problem is cast in terms of electromagnetic potentials, the uniqueness of which is enforced by the choice of Coulomb's gauge. A PN - PN-2 approach ensures the solenoidal...conference paper 2006
