Extreme Lagrangian acceleration in confined turbulent flow.
A Lagrangian study of two-dimensional turbulence for two different geometries, a periodic and a confined circular geometry, is presented to investigate the influence of solid boundaries on the Lagrangian dynamics. It is found that the Lagrangian acceleration is even more intermittent in the confined domain than in the periodic domain. The flatness of the Lagrangian acceleration as a function of...

15 صفحه اولAcceleration-driven variable- density turbulent flow
We discuss turbulent dynamics and mixing of a variable-density flow subject to a uniformacceleration field. The flow resulting from initial misalignments of pressure and density gradients is investigated for small to large density ratios, with evidence that the smalldensity ratio flow is described by the Boussinesq approximation. A new shear-layer growth rate is reported. Spectra collapse when ...
متن کاملTurbulent Flow in a Micro-channel
Turbulent flow of water in a narrow gap of an emulsifier is investigated experimentally using micro-PIV (micro Particle Image Velocimetry) technique and compared with numerical predictions performed using the commercial code Fluent. The purpose of the investigations is to develop a procedure for wellcontrolled generation of mono-disperse suspension of micro droplets. These droplets will form a ...
متن کاملLagrangian statistics in turbulent channel flow
The Lagrangian dispersion of fluid particles in inhomogeneous turbulence is investigated by a direct numerical simulation of turbulent channel flow. Lagrangian velocity and acceleration along a particle trajectory are computed by employing several interpolation schemes. Among the schemes tested, the four-point Hermite interpolation in the homogeneous directions combined with Chebyshev polynomia...
