Simulating the effects of equation of state on blast-wave driven interface morphology

Blast-wave-driven instabilities are vital for studying the dynamics of HED systems, such as high-energy plasma jets, supernova remnants, ICF, and the development of fundamental hydrodynamic instabilities. Laser plasma ablation experiments are a promising method for creating analogous supersonic outflows under HED conditions. In the past, it has been difficult to diagnose specific structures of these outflows due to limitations in diagnostic capabilities and computational tools. Recent experiments at OMEGA, utilizing a newly developed radiography system, have revealed the formation of a single-mode blast-driven instability characterized by bubbles, small-scale spike morphology, and turbulent mixing. In this work, we present high-resolution HYDRA simulations exploring the impact of equation of state models on the formation of bubbles and microjets in the context of perturbed interfaces driven by shock and blast waves. This study will benchmark our simulation capabilities by recreating experimental data presented by Nilson et al (2025). These simulations help ensure that only the highest-quality targets are deployed for OMEGA experiments and that key target features are accurately quantified.
