June Visitors


Jesse Quinlan

  • 5/20/13–6/14/13
  • 8351 Visiting Student
  • Hosted by Joe Oefelein

Jesse Quinlan, a graduate student at the University of Virginia (UV) who is also affiliated with NASA Langley Research Center, collaborated with researchers at the CRF over several weeks on a project to help develop combustion models applicable to the supersonic combustion processes typically encountered in scramjet engines. Specifically, Jesse demonstrated use of flamelet-based combustion closure to model the complex processes inside an experimental scramjet engine by performing extensive comparisons between simulations and companion experimental data. Currently the recipient of a NASA Space Technology Research Fellowship, Jesse conducts research on applying advanced computational fluid dynamics in actual scramjet engine geometries, working closely with Professor James C. McDaniel at UV and Rober Baurle and Tom Drozda at NASA.


Louise Lu

  • 2/25/13–6/22/13
  • 8351 Visiting Student
  • Hosted by Jonathan Frank

Louise Lu, a Sandia Campus Executive Graduate Research Fellow, spent four months working in the Advanced Imaging Laboratory with Jonathan Frank on the development of a technique for simultaneous temperature and velocity field measurements using thermographic phosphors. This collaborative project with Professor Volker Sick at the University of Michigan is aimed at extending a single-camera 3D velocity field measurement technique recently developed in Professor Sick’s group. This new capability, which enables joint measurements of velocity and temperature at high repetition rates, would be particularly valuable for studying transport processes in systems with limited optical access, such as internal combustion engines.


Xiaoying Han

  • 6/10/13–6/18/13
  • 8351 Visiting Researcher
  • Hosted by Habib Najm

Xiaoying Han, a professor of mathematics at Auburn University in Auburn, Alabama, came to the CRF for a second time to work for a week with Habib Najm on the development of methods for model reduction in stochastic chemical systems. Stochastic effects are relevant in chemical systems involving small numbers of molecules, with potential applications in catalysis and biology.  Professor Han is focused on developing the theoretical framework for model reduction in these systems, and plans to continue her collaboration with the CRF remotely and on future visits.


Mauro Valorani

  • 6/24/13–6/28-13
  • 8351 Visiting Researcher
  • Hosted by Habib Najm

On a visit to the CRF from the University of Rome, Professor Mauro Valorani worked with Habib Najm on the development of methods for uncertainty quantification in chemical systems. He will continue to bring his expertise in dynamical analysis of chemical system models to bear in this undertaking in the months ahead, working toward the goal of enabling predictive reacting flow computations with quantified uncertainty.
