Velocity Distribution Associated With EUV Disturbances Caused by Eruptive MFR
Frontiers in Astronomy and Space Sciences, 2021 Extreme ultraviolet (EUV) disturbances are ubiquitous during eruptive phenomena like solar flare and Coronal Mass Ejection (CME). In this work, we have performed a three-dimensional (3D) magnetohydrodynamic numerical simulation of CME with an analytic ...

FluidsThe purpose of this work is to explore the potential of deep reinforcement learning (DRL) as a black-box optimizer for turbulence model identification. For this, we consider a Reynolds-averaged Navier–Stokes (RANS) closure model of a round turbulent jet ...

Instabilities in mimetic matter perturbations [PDF]
, 2017 We study cosmological perturbations in mimetic matter scenario with a general higher derivative function. We calculate the quadratic action and show that both the kinetic term and the gradient term have the wrong sings.

A simple analytical model to study and control azimuthal instabilities in annular combustion chambers [PDF]
, 2012 This study describes a simple analytical method to compute the azimuthal modes appearing in annular combustion chambers and help analyzing experimental, acoustic and LES (Large Eddy Simulation) data obtained in these combustion chambers. It is based on

Electron Temperature Anisotropy Effects on Alpha/Proton Instability in the Solar Wind
Universe, 2022 In situ recordings by the solar Wind spacecraft reveal the ubiquitousness of alpha particles, whose drift velocities to the background proton vα are generally less than or equal to the local Alfvén velocity vA.

Computational Fluid Dynamics Approach for Oscillating and Interacting Convective Flows
Fluids, 2022 The oscillation and collective behavior of convective flows is studied by a computational fluid dynamics approach. More specifically, the rising dynamics of heated fluid columns is simulated in gravitational field using a simplified 2D geometry.

Nonlinear Effects on the Precessional Instability in Magnetized Turbulence
Atmosphere, 2019 By means of direct numerical simulations (DNS), we study the impact of an imposed uniform magnetic field on precessing magnetohydrodynamic homogeneous turbulence with a unit magnetic Prandtl number.

The instability of stabilization [PDF]
Proceedings of the National Academy of Sciences, 2012 Actin filaments and microtubules control the shape of cells and organize their contents. The proteins that form these cytoskeletal polymers were identified and isolated decades ago—actin in 1942 (1) and tubulin in 1968 (2)—but we still argue about some of their basic properties. New work from Niedermayer et al. (3), however, puts us on the right track,
