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).

Project VISTRATU 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

Francesco Di Maiolo, Anna Painelli Intermolecular Energy Transfer in Real Time DOI The realtime 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 threedimensional kinetic simulation of the laserdriven 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 nonzero ∇ n x ∇ T and, hence, a magnetic field. The blue arrows represent the electron current, showing the socalled fountain effect.
