“TurEmu – The physics of (turbulent) emulsions”
High-resolution 3d visualisation of a stabilised emulsion with ~75% volume fraction for the dispersed droplet phase in a 5123 lattice produced via turbulent stirring. A complex interfaces structure is clearly visible with non-spherical droplets.

“Jet/ambient interaction in low-power radiosources”

Top: radio image at 4.6 GHz of 3C 465, from the NRAO VLA Archive Survey (counter clockwise by 145) showing the typical morphology of Wide Angle Tail sources. The resolution is 400 and the field of view is 20 70, corresponding to 70 250 kpc.
Bottom: 3D MHD simulations of low power AGN jets, cut in the (y; z) plane of the (smoothed) brightness distribution in arbitrary units at the evolution time t=5 10^7 years

We investigated the effects of an intense coronal activity on the disk of a classical T Tauri Star. We modeled a magnetized protostar surrounded by an accretion disk through 3D magnetohydrodinamic simulations.

2D images extracted from simulations of driven subsonic turbulence.
These were performed using a standard Lagrangian SPH code (left) and an improved scheme based on an integral approach (right).
From top to bottom: density (top), velocity (middle) and curl of the velocity (bottom). From Valdarnini (2016, ApJ, 831, 103).

Turbulence structures in a viscosity stratified turbulent channel flow, at the top wall, turbulence is largely modulated while, by opposite, at the bottom wall a strong turbulence activity is found.
Results are obtained from Direct Numerical Simulation (DNS) of turbulence coupled with a Phase Field Method (PFM) to describe the interfacial phenomena.

Large Eddy Simulation of Highly Turbulent Compressible Gas

Jets Influence of Mach and Reynolds Numbers on the Fluid Dynamic Characteristics of Turbulent Jets
LES of gas jets with Reynolds number equal to 10000: vorticity contour plots for different Mach numbers. The vorticity intensity decreases along the edge of the potential core with increasing Mach, thus causing an increase of the core length.

Simulation of ion transport through nanopores with Brownian dynamics

In a multiscale modeling framework, collaborating parties with complementary skills simulate ion transport through ion channels and nanopores using models (from all-atom to goarse-grained) studied by computational techniques fitting model resolution.

Intermolecular Energy Transfer in Real Time DOI
The real-time dynamics of the Resonance Energy Transfer (RET) between two organic chromophores is calculated in a model where each dye is described in terms of two electronic states coupled to a single vibrational quantum coordinate and RET is driven by electrostatic intermolecular interactions. The nonadiabatic dissipative dynamics of the RET pair coupled to a Redfield bath describes the weak coupling (Fӧrster) RET, occurring from the vibrationally relaxed energy donor, as well as the strong coupling RET, occurring from vibrationally hot states.

Nitin Shukla
First three-dimensional kinetic simulation of the laser-driven Biermann battery effect.
The picture illustrates the interaction between an intense laser pulse (light orange) and an ionized plasma target (blue surface), generating a strong toroidal magnetic field (dark orange), via the Bierman battery mechanism. Indeed, as a consequence of the interaction, the expansion of the plasma occurs in a direction perpendicular to the electron heating, thus giving rise to a non-zero ∇ n x ∇ T and, hence, a magnetic field. The blue arrows represent the electron current, showing the so-called fountain effect.
