On viscid-inviscid interactions of a pair of bubbles rising near the wall
Kazuki Maeda, Masanobu Date, Kazuyasu Sugiyama +2
Series of experiments on turbulent bubbly channel flows observed bubble clusters near the wall which can change large-scale flow structures. To gain insights into clustering mechan…
Lattice Boltzmann Simulations of Droplet formation in confined Channels with Thermocapillary flows
A. Gupta, M. Sbragaglia, D. Belardinelli +1
Based on mesoscale lattice Boltzmann simulations with the "Shan-Chen" model, we explore the influence of thermocapillarity on the break-up properties of fluid threads in a microflu…
Flow states in two-dimensional Rayleigh-Bénard convection as a function of aspect-ratio and Rayleigh number
Erwin P. van der Poel, Richard J. A. M. Stevens, Kazuyasu Sugiyama +1
In this numerical study on two-dimensional Rayleigh-Bénard convection we consider in aspect ratio samples. We focus on several case…
Horizontal Structures of Velocity and Temperature Boundary Layers in 2D Numerical Turbulent Rayleigh-Bénard Convection
Quan Zhou, Kazuyasu Sugiyama, Richard J. A. M. Stevens +3
We investigate the structures of the near-plate velocity and temperature profiles at different horizontal positions along the conducting bottom (and top) plate of a Rayleigh-Bénard…
Flow reversals in thermally driven turbulence
Kazuyasu Sugiyama, Rui Ni, Richard J. A. M. Stevens +7
We analyze the reversals of the large scale flow in Rayleigh-Bénard convection both through particle image velocimetry flow visualization and direct numerical simulations (DNS) of…
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…
