Nichtlineare Stabilitätsanalyse der3D-Couette-Strömung unter Berücksichtigung derEnergietransfererhaltung
Der Übergang von der laminaren ebenen Couette-Strömung in den Intermittenzbereich wird im Rahmen einer 108-dimensionalen Galerkindarstellung in Orr-Sommerfeld- und Squire-Moden untersucht. Im Reynoldzahlbereich 325<= R <= 350 wird ein deutliches Übergangsverhalten gefunden; des weiteren wird auch …

Helical magnetorotational instability in MHD Taylor-Couette flow
… today such setup is usually referred as a Taylor-Couette flow. To prove experimentally the existence of MRI in a magnetized Taylor-Couette flow is a demanding task and different MHD groups around the world try to achieve it. The main problem lies in the fact that laboratory liquid metals which are …

Untersuchungen zur Blutschädigung durch laminare Strömung im Couette-System
Blood damage of artificial systems within the circulatory system still remains a major problem despite of enormous research activities in this area. Forces acting on blood corpuscles due to non physiological flow conditions, partially in combination with artificial surfaces, are considered as main …

Modeling and Simulation of Molecular Couette Flows and Related Flows
<p>In this thesis, molecular Couette flow is clearly defined and the modeling and simulation of this kind of flow is systematically investigated. First, the integral equations for the velocity of gaseous Couette flow and related flows are derived from linearized Boltzmann BGK equation with Maxwell …

Instability and mixing in a turbulent stratified Taylor-Couette Flow
… in a stably stratified turbulent Taylor-Couette flow, which is the flow in the annular region of two co-axial cylinders, both capable of rotating at different speeds independently, in the presence of vertical stable stratification. Oglethorpe (2014) found that, for an initially linearly …

A dynamical-systems approach to understanding turbulence in plane Couette flow
… development of a model for the dynamics of plane Couette flow based on the theory. The proposed model is essentially a set of low-dimensional models for the local dynamics of the periodic orbits of the Navier-Stokes equations with plane Couette boundary conditions. We considered various aspects of …

Effect of self-stratification of sediment suspensions in turbulent plane Couette flow
… equilibrium sediment-laden plane turbulent Couette flow is presented in the dissertation. Analysis has been made based on a mixing length hypothesis, and numerical simulations have been conducted with an algebraic turbulence closure model and a stratification-corrected k- Reynolds Averaged …

Der Einfluss von laminaren Strömungen und Sekundärströmungen im Taylor-Couette-System auf die Thrombozyten
… are merely investigated. Therefore a Taylor-Couette flow model was developed to generate defined blood flow either with laminar or vortical flow pattern at the same shear rate. Platelet adhesion and activation were investigated as markers for thrombogenicity. Adhesion of resting platelets is …

Rheological properties, stochastic characteristics, and second law violations of atomic fluids in Couette flow
Fluids treated as a discrete collection of particles rather than as a continuum, exhibit exotic properties under shear at sub-continuum scales. For instance, at a critical strain-rate, the fluid becomes non-Newtonian owing to an ordering transition and the thermodynamic entropy production can be …

Untersuchung der Energieratenbilanz der dreidimensionalen, ebenen Couette-Strömung bei Simulation mit der endlichen Galerkin-Methode
Die kinetische Energie der ebenen Couette-Strömung wird durch die externe Leistung der mit konstanter Geschwindigkeit bewegten parallelen Platten und interne Dissipation bestimmt. Die Gültigkeit der entsprechenden Energiebilanz bei Galerkin-Approximationen wird untersucht. Das Geschwindigkeitsfeld …
