Computational and experimental analysis of a U-6w/oNb vacuum consumable arc remelted ingot. A progress report for the Sandia macrosegregation study
A computer code (ZAP) has been developed to simulate the thermodynamic, magnetohydrodynamic, and fluid flow conditions in the liquid and solid-liquid regions of a solidifying ingot during vacuum consumable arc remelting. The code is coupled and constrained with experimentally determined measurements of boundary conditions and melt parameters such as melt rate, melt current, and melt time. The work reported presents one preliminary step in the coupled experimental-numerical process. A 538 kg U-6w/oNb ingot was remelted to obtain regions of constant melting current of 2 through 6 kA in 1 kA increments. The melt was simulated numerically using inputs for the code that were obtained from this experiment. Results of this numerical simulation are compared to experimental results obtained from ingot radiography and chemical analysis.
