Droplet size distribution in homogeneous isotropic turbulence
Prasad Perlekar, Luca Biferale, Mauro Sbragaglia +2
We study the physics of droplet breakup in a statistically stationary homogeneous and isotropic turbulent flow by means of high resolution numerical investigations based on the mul…
Breakdown of the large-scale wind in Γ=1/2 rotating Rayleigh-Bénard flow
Richard J. A. M. Stevens, Herman J. H. Clercx, Detlef Lohse
Experiments and simulations of rotating Rayleigh-Bénard convection in cylindrical samples have revealed an increase in heat transport with increasing rotation rate. This heat trans…
Inverse energy cascade in three-dimensional isotropic turbulence
Luca Biferale, Stefano Musacchio, Federico Toschi
In turbulent flows kinetic energy is spread by nonlinear interactions over a broad range of scales. Energy transfer may proceed either toward small scales or in the reverse directi…
Convection in multiphase flows using Lattice Boltzmann methods
L. Biferale, P. Perlekar, M. Sbragaglia +1
We present high resolution numerical simulations of convection in multiphase flows (boiling) using a novel algorithm based on a Lattice Boltzmann method. We first validate the ther…
Finite-size effects lead to supercritical bifurcations in turbulent rotating Rayleigh-Bénard convection
Stephan Weiss, Richard J. A. M. Stevens, Jin-Qiang Zhong +3
In turbulent thermal convection in cylindrical samples of aspect ratio Γ= D/L (D is the diameter and L the height) the Nusselt number Nu is enhanced when the sample is rotated abou…
The role of Stewartson and Ekman layers in turbulent rotating Rayleigh-Bénard convection
Rudie P. J. Kunnen, Richard J. A. M. Stevens, Jim Overkamp +3
When the classical Rayleigh-Bénard (RB) system is rotated about its vertical axis roughly three regimes can be identified. In regime I (weak rotation) the large scale circulation (…
Effect of aspect-ratio on vortex distribution and heat transfer in rotating Rayleigh-Bénard convection
Richard J. A. M. Stevens, Jim Overkamp, Detlef Lohse +1
Numerical and experimental data for the heat transfer as function of the Rossby number Ro in turbulent rotating Rayleigh-Bénard convection are presented for Prandtl number Pr=4.38…
Effect of Plumes on Measuring the Large Scale Circulation in Turbulent Rayleigh-Bénard Convection
Richard J. A. M. Stevens, Herman J. H. Clercx, Detlef Lohse
We studied the properties of the large-scale circulation (LSC) in turbulent Rayleigh-Bénard (RB) convection by using results from direct numerical simulations in which we placed a…
Microfluidic propulsion by the metachronal beating of magnetic artificial cilia: a numerical analysis
Syed Khaderi, Jaap den Toonder, Patrick Onck
In this work we study the effect of metachronal waves on the flow created by magnetically-driven plate-like artificial cilia in microchannels using numerical simulations. The simul…
Tensorial slip of super-hydrophobic channels
Sebastian Schmieschek, Aleksey V. Belyaev, Jens Harting +1
We describe a generalization of the tensorial slip boundary condition, originally justified for a thick (compared to texture period) channel, to any channel thickness. The eigenval…
Dynamic Multiscaling in Two-dimensional Fluid Turbulence
Samriddhi Sankar Ray, Dhrubaditya Mitra, Prasad Perlekar +1
We obtain, by extensive direct numerical simulations, time-dependent and equal-time structure functions for the vorticity, in both quasi-Lagrangian and Eulerian frames, for the dir…
Axially-homogeneous Rayleigh-Benard convection in a cylindrical cell
Laura E. Schmidt, Enrico Calzavarini, Detlef Lohse +2
Previous numerical studies have shown that the "ultimate regime of thermal convection" can be attained in a Rayleigh-Benard cell when the kinetic and thermal boundary layers are el…
Multi-Time Multi-Scale Correlation Functions in Hydrodynamic Turbulence
Luca Biferale, Enrico Calzavarini, Federico Toschi
High Reynolds numbers Navier-Stokes equations are believed to break self-similarity concerning both spatial and temporal properties: correlation functions of different orders exhib…
Analytical and experimental characterization of a miniature calorimetric sensor in pulsatile flow
H. Gelderblom, A. van der Horst, J. R. Haartsen +3
The behaviour of a miniature calorimetric sensor, which is under consideration for catheter-based coronary artery flow assessment, is investigated in both steady and pulsatile tube…
