Measuring nonextensitivity parameters in a turbulent Couette-Taylor flow.

چکیده
We investigate probability density functions of velocity differences at different distances r measured in a Couette-Taylor flow for a range of Reynolds numbers Re. There is good agreement with the predictions of a theoretical model based on nonextensive statistical mechanics (where the entropies are nonadditive for independent subsystems). We extract the scale-dependent nonextensitivity parameter q(r,Re) from the laboratory data.

Turbulent Bursts in Couette-Taylor Flow.
We present a physical explanation of turbulent bursts in the flow between concentric, rotating cylinders (Couette-Taylor flow), based on fully resolved direct numerical calculations. The bursts are a temporal oscillation between a spatially laminar flow and turbulence, discovered experimentally by Hamill et al. The onset of turbulence is shown to be due to a linear instability of the spiral flo...
متن کاملTransient turbulence in Taylor-Couette flow.
Recent studies have brought into question the view that at sufficiently high Reynolds number turbulence is an asymptotic state. We present direct observation of the decay of turbulent states in Taylor-Couette flow with lifetimes spanning five orders of magnitude. We also show that there is a regime where Taylor-Couette flow shares many of the decay characteristics observed in other shear flows,...
متن کاملBubbly turbulent drag reduction is a boundary layer effect.
In turbulent Taylor-Couette flow, the injection of bubbles reduces the overall drag. On the other hand, rough walls enhance the overall drag. In this work, we inject bubbles into turbulent Taylor-Couette flow with rough walls (with a Reynolds number up to 4 x 10(5), finding an enhancement of the dimensionless drag as compared to the case without bubbles. The dimensional drag is unchanged. As in...
متن کاملLarge-scale finite-wavelength modulation within turbulent shear flows.
We show that turbulent "spirals" and "spots" observed in Taylor-Couette and plane Couette flow correspond to a turbulence-intensity modulated finite-wavelength pattern which in every respect fits the phenomenology of coupled noisy Ginzburg-Landau (amplitude) equations with noise. This suggests the existence of a long-wavelength instability of the homogeneous turbulence regime.
متن کاملMean Flow of Turbulent - Laminar Patterns in Plane Couette Flow By DWIGHT BARKLEY
A turbulent-laminar banded pattern in plane Couette flow is studied numerically. This pattern is statistically steady, is oriented obliquely to the streamwise direction, and has a very large wavelength relative to the gap. The mean flow, averaged in time and in the homogeneous direction, is analysed. The flow in the quasi-laminar region is not the linear Couette profile, but results from a non-...
