A Taylor-Couette flow hemofilter, referred to as vortex flow plasmapheretic reactor (VFPR), has been designed to treat blood plasma with a fluidized-bed of small porous particles (∼micron). The classic Taylor-Couette flow of non-magnetic fluid has been a computatio16 and experimen18,19 paradigm to investigate a variety of nonlinear and complex dynamical phenomena.

The formation of turbulent patterns in plane Couette flow is investigated near the onset of transition, using numerical simulation in a very large domain of size h × 2 h × on a maximum observation time of 20 inertial units, the threshold for the appearance of sustained turbulent motion is Re c = ± 1. For Re c turbulent-banded patterns . Chao and Quan () work can be considered as baseline for future flow studies, they worked on different experimental techniques for turbulent Rayleigh Benard convection and Taylor Couette flow. These experimental techniques are quite helpful for understanding the flow structure and flow characteristics [ 13 ].

The phase dynamics of flows in the Taylor–Couette system have been studied by applying a forced modulation to the upper boundary of a large aspect ratio concentric cylinder system. In a one phase variable case, the Taylor vortex flow, the perturbations diffuse along the axial direction and the pattern’s response is well described by a simple diffusion model. Taylor–Couette flows have been widely studied in part due to the enhanced mixing performance from the variety of hydrodynamic flow states accessible. These process improvements have been demonstrated despite the traditionally limited injection mechanisms from the complexity of the Taylor–Couette geometry.

Ordered and turbulent patterns in Taylor-Couette flow / ed. by David Andereck and F. Hayot Date: Editeur / Publisher: New York [etc.]: Plenum Press, cop. Abstract. Intermittent turbulence, the coexistence of laminar and turbulent flow 1, is well known to exist in circular Couette flow when the two cylinders counter-rotate particular, the turbulent and laminar regions may organize into the Spiral Turbulence pattern (alternating regions of laminar and turbulent flow which wrap around the axis of the cylinders to form a Cited by: 5.

The effect of gas bubbles on Taylor–Couette flow patterns in the transition from laminar to weakly turbulent vortex flow is investigated by quasi-2D and 3D CFD simulation.

The CFD model is based on the Eulerian–Eulerian two-fluid approach with constitutive closures for inter-phase forces and liquid turbulence and validated by comparison.

Abstract. The transition to turbulence in the Taylor Couette experiment has been extensively studied in the past by several groups. This flow with its simple geometry produces a large number of different flow patterns, depending on the gap radius ratio, the Reynolds numbers of the rotation of both cylinders and the flow history the case with the outer cylinder at rest.

Our experiments have revealed an unexpected array of bifurcation phenomena. 6 This paper will explain the techniques used to discover the bifurcations in the flow, present a bifurcation map of the Taylor-Couette system subject to a Coriolis force, and finally, discuss some of the more interesting features revealed by the map.

Abstract. Taylor-Couette flow subjected to a Coriolis force is a rich pattern-forming system. 1–5 The Coriolis force is applied by rotating a Couette apparatus so that the axis of rotation for the system is. orthogonal to the common axis of the cylinders (see figure 1).

This orientation produces a nonaxisymmetric Coriolis force through the interaction of the rotation of the system with the. and re-formation of near-wall coherent structures in turbulent Couette flow, Duguet et al.
