A quadratic Reynolds stress development for the turbulent Kolmogorov flow

no code implementations13 Jan 2021 Wenwei Wu, Francois G. Schmitt, Enrico Calzavarini, Lipo Wang

We study the three-dimensional turbulent Kolmogorov flow, i. e. the Navier-Stokes equations forced by a low-single-wave-number sinusoidal force in a periodic domain, by means of direct numerical simulations.

Ice front shaping by upward convective current

1 code implementation22 Dec 2020 Ziqi Wang, Linfeng Jiang, Yihong Du, Chao Sun, Enrico Calzavarini

We propose a boundary-layer model and a buoyancy-intensity model which account for the main features of the ice morphology.

Rotational dynamics of bottom-heavy rods in turbulence from experiments and numerical simulations

1 code implementation10 Dec 2020 Linfeng Jiang, Cheng Wang, Shuang Liu, Chao Sun, Enrico Calzavarini

We successfully perform the three-dimensional tracking in a turbulent fluid flow of small asymmetrical particles that are neutrally-buoyant and bottom-heavy, i. e., they have a non-homogeneous mass distribution along their symmetry axis.

Settling of inertial particles in turbulent Rayleigh-Benard convection

1 code implementation11 May 2020 Vojtech Patocka, Enrico Calzavarini, Nicola Tosi

The settling behaviour of small inertial particles in turbulent convection is a fundamental problem across several disciplines, from geophysics to metallurgy.

Rotation of anisotropic particles in Rayleigh-Bénard turbulence

1 code implementation30 Nov 2019 Linfeng Jiang, Enrico Calzavarini, Chao Sun

Inertialess anisotropic particles in a Rayleigh-B\'enard turbulent flow show maximal tumbling rates for weakly oblate shapes, in contrast with the universal behaviour observed in developed turbulence where the mean tumbling rate monotonically decreases with the particle aspect ratio.
