Intermittency and collisions of fast sedimenting droplets in turbulence
Itzhak Fouxon, Seulgi Lee, Changhoon Lee
We study theoretically and numerically spatial distribution and collision rate of droplets that sediment in homogeneous isotropic Navier-Stokes turbulence. It is assumed that typic…
Unsupervised deep learning for super-resolution reconstruction of turbulence
Hyojin Kim, Junhyuk Kim, Sungjin Won +1
Recent attempts to use deep learning for super-resolution reconstruction of turbulent flows have used supervised learning, which requires paired data for training. This limitation…
Deep unsupervised learning of turbulence for inflow generation at various Reynolds numbers
Junhyuk Kim, Changhoon Lee
A realistic inflow boundary condition is essential for successful simulation of the developing turbulent boundary layer or channel flows. Recent advances in artificial intelligence…
Inhomogeneous distribution of droplets in cloud turbulence
Itzhak Fouxon, Yongnam Park, Roei Harduf +1
We solve the problem of spatial distribution of inertial particles that sediment in turbulent flow with small ratio of acceleration of fluid particles to acceleration of gravity $g…
Universal statistics of density of inertial particles sedimenting in turbulence
Itzhak Fouxon, Yongnam Park, Roei Harduf +1
We solve the problem of spatial distribution of inertial particles that sediment in Navier-Stokes turbulence with small ratio of acceleration of fluid particles to acceleratio…
Modification of particle-laden near-wall turbulence: effect of Stokes number
Junghoon Lee, Changhoon Lee
Turbulent channel flows laden with particles are investigated using direct numerical simulation with a point-force approximation for small, heavy particles with a diameter smaller…
Gravity-driven clustering of inertial particles in turbulence
Yongnam Park, Changhoon Lee
We report a new kind of particle clustering caused purely by gravity, discovered in our simulation of particle-laden turbulence. Clustering in a vertical strip pattern forms when s…
