This work presents computational modeling of hypersonic flow and material response in the Energetic Material Interaction Tunnel (EMIT) at Lawrence Livermore National Laboratory. Using the LeMANS hypersonic flow code coupled with the Firefly material response code, we simulate and analyze the complex 3D flow and laser-material interactions relevant to hypersonic flight conditions. The study maps EMIT facility flows to equivalent flight scenarios, evaluates gas and heat flow around test articles, and compares convective and laser-induced heating. Results demonstrate the complexity of modeling high-energy, reactive environments, the ability to capture experimental diagnostics, and the constraints the tunnel setup presents at varying altitude conditions. Ongoing work focuses on refining material models, integrating experimental data, and validating simulations to advance the predictive capability for hypersonic material response in ground-based facilities.
