Modeling compressed turbulent plasma with rapid viscosity variations

We propose two-equation models in order to capture the dynamics of a turbulent plasma undergoing compression and experiencing large viscosity variations. The account for possible relaminarization phases rapid changes through closures dependent on Reynolds Froude numbers. These are determined from data-driven approach using eddy-damped quasi-normal Markovian simulations. best model is able mimic various self-similar regimes identified Viciconte et al. [Phys. Rev.
