conditions of temperature and pressure. Understanding the growth and properties of
hydrodynamic instabilities and the transition into turbulence is important in many HED
processes and also yields insights into other areas where hydrodynamic instabilities occur. In
contrast to classical fluids experiments, examining hydrodynamic instabilities in the HED regime
poses novel challenges. HED experiments are expensive and often performed at oversubscribed
facilities. Additionally, there are many limitations for the available diagnostics and experiments
are typically multi-physics in nature. Such complexity means that modeling can become
prohibitively expensive. Improving the models from limited experimental and high-fidelity
simulation data is therefore of great importance. We will discuss the use of statistical techniques
on a large suite of 2D xRAGE simulations of multimode Richtmyer-Meshkov and Rayleigh-
Taylor experiments performed on Omega-EP in order to better understand how our experimental
data can be used to understand turbulence models in the HED regime.
