Quantification of the performance of chaotic micromixers on the basis of finite time Lyapunov exponents
Aniruddha Sarkar, Ariel Narváez, Jens Harting
Chaotic micromixers such as the staggered herringbone mixer developed by Stroock et al. allow efficient mixing of fluids even at low Reynolds number by repeated stretching and fold…
Statistics of polymer extensions in turbulent channel flow
Faranggis Bagheri, Dhrubaditya Mitra, Prasad Perlekar +1
We present direct numerical simulations of turbulent channel flow with passive Lagrangian polymers. To understand the polymer behavior we investigate the behavior of infinitesimal…
Numerical simulations of compressible Rayleigh-Taylor turbulence in stratified fluids
A. Scagliarini, L. Biferale, M. Sbragaglia +2
We present results from numerical simulations of Rayleigh-Taylor turbulence, performed using a recently proposed lattice Boltzmann method able to describe consistently a thermal co…
Persistence Problem in Two-Dimensional Fluid Turbulence
Prasad Perlekar, Samriddhi Sankar Ray, Dhrubaditya Mitra +1
We present a natural framework for studying the persistence problem in two-dimensional fluid turbulence by using the Okubo-Weiss parameter to distinguish between vortical and e…
Impact of trailing wake drag on the statistical properties and dynamics of finite-sized particle in turbulence
Enrico Calzavarini, Romain Volk, Emmanuel Leveque +2
We study by means of an Eulerian-Lagrangian model the statistical properties of velocity and acceleration of a neutrally-buoyant finite-sized particle in a turbulent flow statistic…
Energy Spectra of Quantum Turbulence: Large-scale Simulation and Modeling
Narimasa Sasa, Takuma Kano, Masahiko Machida +3
In simulation of quantum turbulence within the Gross-Pitaevskii equation we demonstrate that the large scale motions have a classical Kolmogorov-1941 energy spectrum E(k)…
Direct numerical simulations of statistically steady, homogeneous, isotropic fluid turbulence with polymer additives
Prasad Perlekar, Dhrubaditya Mitra, Rahul Pandit
We carry out a direct numerical simulation (DNS) study that reveals the effects of polymers on statistically steady, forced, homogeneous, isotropic fluid turbulence. We find clear…
Population dynamics at high Reynolds number
Prasad Perlekar, Roberto Benzi, David R. Nelson +1
We study the statistical properties of population dynamics evolving in a realistic two-dimensional compressible turbulent velocity field. We show that the interplay between turbule…
Simulations of slip flow on nanobubble-laden surfaces
Jari Hyväluoma, Christian Kunert, Jens Harting
On microstructured hydrophobic surfaces, geometrical patterns may lead to the appearance of a superhydrophobic state, where gas bubbles at the surface can have a strong impact on t…
Quantitative analysis of numerical estimates for the permeability of porous media from lattice-Boltzmann simulations
Ariel Narváez, Thomas Zauner, Frank Raischel +2
During the last decade, lattice-Boltzmann (LB) simulations have been improved to become an efficient tool for determining the permeability of porous media samples. However, well kn…
Lattice Boltzmann simulations of liquid flilm drainage between smooth surfaces
Christian Kunert, Jens Harting
Exploring the hydrodynamic boundary of a surface by approaching a colloidal sphere and measuring the occurring drag force is a common experimental technique. However, numerous para…
Boundary layers in rotating weakly turbulent Rayleigh-Benard convection
Richard J. A. M. Stevens, Herman J. H. Clercx, Detlef Lohse
The effect of rotation on the boundary layers (BLs) in a Rayleigh-Benard (RB) system at a relatively low Rayleigh number, i.e. , is studied for different Pr by di…
