CTR Year End Review

The objective of CTR continues to be the fundamental understanding of turbulent flows along with the development of physics-based models and predictive tools for multi-scale engineering analysis. The investigations have been supported by a number of different organizations, including programs sponsored by the Department of Energy’s National Nuclear Security Administration (NNSA), Air Force Office of Scientific Research (AFOSR), Office of Naval Research (ONR), National Aeronautics and Space Administration (NASA), National Science Foundation (NSF), as well as industrial partners and international research agencies.

CTR research covers a wide range of topics related to multi-physics effects in turbulent flows. Particle-laden turbulent flow is a common theme of our current core research activities. Interest in this topic has been reinvigorated at Stanford as a result of the recently awarded Predictive Science Academic Alliance Program (PSAAP-II) by the Department of Energy’s NNSA. The overarching problem of the PSAAP-II Center at Stanford involves full-scale computation, and uncertainty-quantification analysis of solar-power receivers based on distributed absorption of thermal radiation by small particles in the bulk of the turbulent co-flowing air. Two-phase flows addressing the dynamics of turbulent liquid-gas interfaces using high-fidelity computations is another core research area. The development of numerical methods and diagnostics tools for flow data analysis is a common theme of CTR research. A significant part of this work is dedicated to wall modeling in turbulent flows, which is a pacing item for large-eddy simulation.

Last year CTR hosted thirteen resident Postdoctoral Fellows, one Research Associate, one Visiting Researcher, and three Senior Research Fellows. Also listed are the members of the CTR Steering Committee which has met quarterly to act on fellowship applications.
