The boiling Twente Taylor-Couette (BTTC) facility: Temperature controlled turbulent flow between independently rotating, coaxial cylinders.
A new Taylor-Couette system has been designed and constructed with precise temperature control. Two concentric independently rotating cylinders are able to rotate at maximum rates of f(i) = ± 20 Hz for the inner cylinder and f(o) = ± 10 Hz for the outer cylinder. The inner cylinder has an outside radius of r(i) = 75 mm, and the outer cylinder has an inside radius of r(o) = 105 mm, resulting in ...
متن کاملSpiral vortices and Taylor vortices in the annulus between rotating cylinders and the effect of an axial flow.
We present numerical simulations of vortices that appear via primary bifurcations out of the unstructured circular Couette flow in the Taylor-Couette system with counter rotating as well as with corotating cylinders. The full, time dependent Navier Stokes equations are solved with a combination of a finite difference and a Galerkin method for a fixed axial periodicity length of the vortex patte...
متن کاملNematic between Coaxial Cylinders
The stability of the equilibrium configurations of a nematic liquid crystal confined between two coaxial cylinders is analysed when a radial electric field is applied and the flexoelectric effect is taken into account. The threshold for perturbations depending only on the radius r in the cylindrical coordinate system and strong boundary conditions is studied. A new type of orientational transit...
متن کاملThe Hydrodynamic Stability of Inviscid Flow between Coaxial Cylinders.
where R1 and R2 are, respectively, the radii of the inner and the outer cylinders. The presence of viscosity inhibits the onset of instability and condition (3) must be violated by a certain determinate extent before instability can arise. The extent of this inhibition has been considered by a number of authors since G. I. Taylor first investigated the problem.1 The equations of viscous flow al...
متن کاملThe Onset of Taylor-Like Vortex in the Flow Induced by an Impulsively Started Rotating Cylinder
The onset of instability induced by impulsively started rotating cylinder was first investigated experimentally by Chen and Christensen [1]. The initial laminar flow evolves into a secondary flow pattern which consists of a series of Taylor-like vortices. In this transient boundary-layer system the critical time tc to mark the onset of secondary motion becomes an important question. This proble...
