Interfacial area in gas–liquid Couette–Taylor flow reactor

Experimental Thermal and Fluid Science, 2004
Abstract In this study the specific interfacial area (gas–liquid) generated within a stirred tank and Couette–Taylor–Poiseuille flow (CTPF) reactor was determined for a range rotational speeds, and gas and liquid volumetric flow rates. The specific interfacial area was obtained experimentally using the oxidation sodium dithionite in alkaline solution.

Wave-Number Selection in Rotating Couette-Taylor flow

1984
In nonlinear dissipative systems subjected to an external stress, R, a transition frequently occurs to a state of reduced symmetry having a spatial structure with a characteristic wavelength when R exceeds a critical value Rc. Examples are Rayleigh-Benard convection [1], Taylor-vortex flow [2–4], certain chemical reactions [5], flame-front propagation [

Transition to Turbulence in Couette-Taylor Flow

1979
The Couette-Taylor problem is described in this section and our laser Doppler velocimetry studies of transitions in Couette-Taylor flow are presented in the next section, which also includes a summary of three other recent studies of flow spectra in the transition region.

Extended local balance model of turbulence and Couette-Taylor flow

Physical Review E, 2000
An extended local balance model of turbulence, based on a new transport equation for the dissipation rate with a negative diffusion coefficient, is presented. Analytical solutions for the mean velocity and the dissipation rate for the turbulent Couette-Taylor problem are derived. The dependence of torque on the Reynolds number is obtained.

Dynamical Mechanism and Energy Conversion of the Couette–Taylor Flow

International Journal of Bifurcation and Chaos, 2019
In this paper, we study the dynamical mechanism and energy conversion of the Couette–Taylor flow. The Couette–Taylor flow chaotic system is transformed into the Kolmogorov type system, which is decomposed into four types of torques. Combining different torques, the key factors of chaos generation and the physical interpretation of the Couette–Taylor ...

Influence of surface irregularities on hydrodynamic instabilities in Couette-Taylor and Couette-Taylor-Poiseuille flow

2020
Ce travail porte sur l’étude numérique et expérimentale d’un écoulement de Couette-Taylor dans une géométrie à surfaces rugueuses, afin de détecter l’effet de la rugosité sur les instabilités hydrodynamiques. Dans un premier temps, nous avons effectué une étude de simulation numérique (CFD) 3D dans le cas d’un écoulement de Couette-Taylor sans débit ...
