Location Los Alamos, NM, US
Organization Name XTD-IDA/ Theoretical Design- Integrated Design & Assessment

What You Will Do
The Integrated Design and Assessment (XTD-IDA) group in the X Theoretical Design (XTD) division is seeking motivated candidates for a six-month Graduate Research Assistant (GRA) position simulating small scale mixing in Double Cylinder experiments.
The Double Cylinder experiments are a series of experiments fired at the Sandia Z machine that aim to understand the hydrodynamic development of features in imploding geometries, such as joints in Inertial Confinement Fusion (ICF) capsules. In these experiments, Z is used to implode a pair of concentric cylindrical shells around a central witness rod, with 2D defects placed on the inner shell. These features are unstable and produce spikes that can interact and imprint onto the central rod. The experiments are nominally two dimensional, but simulations of the double shell experiments have found them to be sensitive to 3D effects.
In particular, the focus of this position is to research the effects of small-scale mixing and how it should be modeled in these experiments. This will involve performing 3D Implicit Large Eddy Simulations (ILES) of the experiments using the laboratory's Eulerian xRage code to gauge the computational requirements to properly simulate the mixing. Simulations in the Lagrangian FLAG code are also of interest if time permits. Additionally, 2D and 3D simulations using turbulence models are needed to understand the extent to which these mix effects can be captured in lower cost simulations, and how large-scale thermal instabilities in the exterior of the experiment that drive the mixing should be represented in the mix models. An internal report and/or presentation is required at the end of the six months to document the performed work, and interaction with the broader research community via conferences and journal publications is encouraged.
