Accurate predictive hydrodynamics codes increase the efficiency with which ignition will be achieved at the National Ignition Facility (NIF) [J. W. Hogan et al., J. Nucl. Fus. 41, 567 (2001)]. By validating these codes against well-diagnosed experiments, additional confidence in their predictive capability is attained. This work presents comparisons between the predictive simulations of the Los Alamos hydrocode RAGE [R. M. Baltrusaitus et al., Phys. Fluids 8, 2471 (1996)] and data obtained from cylindrical defect-driven mix experiments conducted on the OMEGA [T. R. Boehly et al., Opt. Commun. 133, 495 (1997)] laser. The results show that RAGE accurately captures much of the bulk hydrodynamics of the experiments. However, persistent discrepancies with respect to the small-scale fluid flows remain.
