Assist in performing experiments and theory on the effects of residual stresses on the adhesion of coatings and thin films on silicon and steel substrates; x-ray diffraction experiments using the Advanced Photon Source to measure residual stresses; and develop techniques, in consultation with staff, to measure surface adhesion energies of the coatings and thin films.

The purpose of the project is the analysis of ANL Café tests that involve flow of molten uranium metal in a trough. The analysis will involve the simulation of the free surface flow of molten metal in the trough, conjugate heat transfer through the trough, and solidification of the molten metal as it cools down. Consistent with the ANL Café tests, the analyses will involve capturing these phenomena for different angles of trough inclination. The melt temperature and composition (U vs. U-Fe alloy) are also important parameters. A natural extension of this effort would be the analysis of molten uranium flow in rod bundle configurations.

The student will support ongoing efforts to develop advanced experiments to be completed by the Argonne Thermofluid Sciences Laboratory as a basis for validation of multidimensional computational fluid dynamics based simulations of advanced reactor component designs.  The student will:
1. Complete an initial training course in the use of the commercial CFD software package Star-CD, including the completion of a series of tutorial problems which introduce capabilities to be used over the remainder of the appointment.
2. Work with supervisors to select a specific experiment reactor component to consider in detailed simulations.
3. Define appropriate geometric parameters and boundary conditions. 
4. Develop a computational model of the selected system.
5. Complete a baseline simulation and a solution verification study to quantify uncertainties based on selected modeling options.
6. Document findings in an internal memo or report which may be used to develop external publications.

Student will help measure bubble-and grain size distributions using micrographs of irradiated U-Mo fuel developed as part of the RERTR program.  Student will also assit in the analysis of the data using mechanistic models for gas behavior that are under development at Argonne.

The student will work on an on-going project to determine the interaction of millimeter waves with the air ions generated by nuclear radiation, which will form the basis for remote radiation detection system using millimeter wave radar.  A laboratory-based system has been put together for standoff measurement of air ions using millimeter wave (MMW) sensor technology.  The system consists of a negative ion generator (NIG) and an ion counter in parallel with a MMW detector system. The student will work with outstanding research personnel’s at Argonne.  This is a great opportunity for a student to learn how to design, test, and integrate a full system for real-time, on-line applications.

The assignee will conduct numerical simulations of fuel cell components in support of the Fuel Cell Systems Modeling and Analysis task that is funded by DOE at Argonne. This research will also complement the work being carried out at the University of Puerto-Mayaguez, a Hispanic Serving Minority Institution, as a subcontractor to Argonne for a DOE-funded research project. Results from this research will help the overall DOE program to develop fuel cell systems for automotive, distributed, and portable power generation.
