Abstract:
This volume contains the 2003 Annual Progress Reports of the postdoctoral fellows and visiting scholars of the Center for Turbulence Research. In 2003 CTR sponsored 19 resident Postdoctoral Fellows, 5 Senior visiting scholars, 4 doctoral students and hosted 9 Research Associates. The volume contains progress reports on a wide range of subjects reflecting the impact of the dynamic subgrid scale model on new application areas, and the close association of CTR with efforts funded at Stanford University by the Department of Energy, the Air Force Office of Scientific Research and the U.S office of Naval Research. The development of core technology for gas turbine application remains the largest component of CTR's effort. This reflects the support received by CTR from NASA's Ultra Efficient Engine Technology Program in turbulent combustion research. Close coordination with the efforts supported by DOE's ASCI program at Stanford enables rapid transfer of progress in fundamental understanding and modeling to realistic aircraft engine simulations. Several reports show progress in simulation of multiphase flows in general, and sprays in particular. Level set methods have been developed to model the primary breakup of sprays, and adaptive level set methods have been applied to study three-dimensional breakup of drops. A new Eulerian-Lagrangian formation shows great potential for the extension of particle methods to the dense regime in sprays. Advances in multiphase flow simulation enabled new studies in other problems such as the Richtmyer-Meshkov instability. Major progress has been made in transferring the multi-phase technology to the unstructured LES code being developed to simulate realistic gas turbine combustors.
