An affordable route to MHD turbulent realizations

Turbulence is an unavoidable chaotic state that characterizes fluids, gases, and plasmas. It finds applications in a variety of contexts from aerodynamics to everyday life. Of special interest for this project is that turbulence is found everywhere in Space: accretion disks, astrophysical jets, solar/ stellar atmospheres and winds. The ubiquitous presence of turbulence makes its study and understanding essential in modern astrophysics. The core of this project is to be able to generate and/or reproduce turbulent realizations of magnetized flows at an affordable cost, compared to state-of-the-art direct numerical simulations available at the moment. As an essential part of this project, we expect to be able to provide confirmations of the generated turbulent states by the means of synthetic imagery and statistical properties (injection scale, dissipation range, power-law dependence). Our approach will be based on the combination of two distinct approaches that builds on recently developed computational tools: BxC and Legolas. The first one exploits geometric properties of turbulent states, the second implements a linear approach to the understanding of turbulence. The combined use of these tools will lead us to unravel the mysteries of turbulent regimes in a variety of astrophysical contexts. We expect our approach to be validated by direct confrontations with both publicly available simulation data and observed turbulent states.
