Weekly Seminar: Fall 2013
Speaker: Prof. Charles V. Meneveau (JHU | MechE)
Title: “Turbulence Research on the Run: A Brief Account of a Sabbatical Year in Australia and Europe”
Date: Friday, September 6, 2013
Time: 11:00 a.m.
Location: Gilman Hall 50 (Marjorie M. Fisher Hall)
In this presentation, I will summarize several results from visits to the University of Melbourne (Australia), Ecole Normale Superieure in Lyon (France), University of Rome "Tor Vergata" (Italy), and EPFL, Lausanne (Switzerland). Topics cover various aspects of turbulence research, ranging from high Reynolds number turbulent boundary layers, modeling tumbling rates of anisotropic particles in turbulence, deformation statistics of droplets in turbulence, and modeling drag forces that arise from wind blowing over icy surfaces using detailed elevation maps measured by EPFL researchers in Antarctica.
Charles Meneveau is the Louis M. Sardella Professor in the Department of Mechanical Engineering at Johns Hopkins University. He also has a joint appointment in the Geography and Environmental Engineering Department and serves as the director of the Center of Environmental and Applied Fluid Mechanics (CEAFM) and as deputy director of the Institute for Data Intensive Engineering and Science (IDIES) at Johns Hopkins. He received his B.S. degree in Mechanical Engineering from the Universidad Técnica Federico Santa María in Valparaíso, Chile, in 1985 and M.S, M.Phil. and Ph.D. degrees from Yale University in 1987, 1988 and 1989, respectively. During 1989/90 he was a postdoctoral fellow at the Stanford University/NASA Ames' Center for Turbulence Research. Professor Meneveau has been on the Johns Hopkins faculty since 1990. His area of research is focused on understanding and modeling hydrodynamic turbulence, and complexity in fluid mechanics in general. He combines experimental, computational and theoretical tools for his research. Special emphasis is placed on the multiscale aspects of turbulence, using appropriate tools such as subgrid-scale modeling, downscaling techniques, fractal geometry, wavelet analysis, and applications to Large Eddy Simulation. The insights that have emerged from Professor Meneveau’s work have led to new numerical models for Computational Fluid Dynamics and applications in engineering and environmental flows.
