Title: Validation of the radiation hydrocode RAGE against defect-driven mix experiments in a compressible, convergent, and miscible plasma system

Abstract

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.

  • The two-dimensional (2-D) radiation-magnetohydrodynamic (R-MHD) code FOREV-2 was developed for modeling of disruptive hot plasma-wall interaction, for calculation of erosion by evaporation of the ITER-FEAT vertical divertor target, and for calculation of the impurity transport in the divertor. FOREV-2 uses a 2 1/2-D MHD model, a 2-D scheme for anisotropic radiation transport, and a solution of the magnetic field equations in the plasma shield for all three components of the magnetic field. Details of FOREV-2 with emphasis on the MHD equations, the equations for the magnetic field, the vaporization model, the angular dependent multigroup radiation transport, and the optical propertiesmore » of plasmas, and validation of FOREV-2 against analytical results are discussed.Moreover, disruption simulation experiments, performed at the plasma gun facilities at TRINITI Troitsk were used for validation of FOREV-2 and for investigations of the MHD of typical plasma shields. From the results of the numerical analysis of the simulation experiments, it is concluded that turbulence in the experimental plasma shields is absent and that the stability of the cold and dense part of the plasma shields, which determines the target erosion, can be adequately modeled by FOREV-2 by use of the classical magnetic field diffusion coefficient. The experimentally observed downstream drift of plasma shields along the surface of the vertical targets is due to the lateral motion of a cold and dense plasma layer close to the target. The observed upstream shift of the erosion profiles of vertical targets is due to reradiation from the expanding plasma shield. Line radiation and an appropriate model for anisotropic radiation transport are necessary for a realistic calculation of the reradiation from carbon plasma shields. Moreover, inclusion of the line radiation allows one to get a realistic radiation cooling after switching off the heating. Target erosion in the simulation experiments is caused by radiation. The agreement between calculated and measured erosion for graphite and quartz demonstrates the adequacy of the calculated 2-D radiative target heat loads.The 2-D numerical analysis of the disruption simulation experiments allows one to conclude that such experiments adequately simulate the tokamak plasma shield properties and its dynamics. The extensive validation exercise of FOREV-2 against disruption simulation experiments gives confidence that the numerical analysis of erosion for the ITER-FEAT vertical targets during the thermal quench phase of a disruption and the impurity production during ELMs and its transport toward the x-point to be performed with FOREV-2 is based on sound principles and covers all important aspects of plasma shield behavior and plasma shield stability.« less
  • In the linear-response approximation, coherently driven microcavity polaritons in the pump-only configuration are expected to satisfy the Landau criterion for superfluidity at either strong enough pump powers or small flow velocities. Here, we solve nonperturbatively the time-dependent Gross-Pitaevskii equation describing the resonantly driven polariton system. We show that, even in the limit of asymptotically large densities, where in linear-response approximation the system satisfies the Landau criterion, the fluid always experiences a residual drag force when flowing through the defect. We explain the result in terms of the polariton lifetime being finite, finding that the equilibrium limit of zero drag canmore » only be recovered in the case of perfect microcavities. In general, both the drag force exerted by the defect on the fluid, as well as the height of Cherenkov radiation, and the percentage of particles scattered by the defect, show a smooth crossover rather than a sharp thresholdlike behavior typical of superfluids which obey the Landau criterion.« less
  • Comparisons between ALOHA code predictions and experimental measurements of reflection coefficients for the two different Lower Hybrid Current Drive (LHCD) antennas (named C2 and C3) in Tore Supra are presented. A large variation of density in front of the antennas was obtained by varying the distance between the plasma and the antennas. Low power (<2 MW/m{sup 2}) was used in order to avoid non-linear effects on the wave coupling. Results obtained with ALOHA are in good agreement with the experimental measurements for both Tore Supra antennas and show that ALOHA is an efficient LH predictive tool.
  • The use of a continuous graphic recording system for flow-component measurement in miscible displacement experiments is described. This system measures and continuously records radioactive tracer concentrations of effluents of miscible displacement columns. The recordings are needed breakthrough curves. The use of the system obviates fraction collectors.
