Chair's Distinguished Lecture: Exploring the Physics of Multi-length Scale Flows at the Molecular Level
Deborah Levin, Professor, Aerospace Engineering Department, The University of Illinois at Urbana-Champaign
There is a general consensus in the hypersonics and aerospace plasma research communities that fundamental modeling of such systems requires a molecular approach. In the last few years, particle and kinetic approaches such as direct simulation Monte Carlo, molecular dynamics, and particle-in-cell have begun to offer new insights into traditional, as well as, non-traditional aerospace systems applications. However, challenges related to the large variations in length and time scales still remain. Two diverse examples that will be presented in the seminar are (1) the kinetic treatment of electrons in space plasmas that cause spacecraft contamination and (2) the rarefaction affects in unsteady shock-boundary layer interactions. Use of new enabling, computational algorithms that take advantage of the heterogeneous hardware environments will be discussed.
About the Speaker
DEBORAH A. LEVIN, Professor of aerospace engineering at the University of Illinois Urbana-Champaign - (UIUC), received her Ph.D. from the California Institute of Technology in chemistry. Before joining PSU in 2000, she held positions at the Institute for Defense Analyses and George Washington University. Her recent research centers concentrate on the modeling of chemically reacting hypersonic flows, radiation from hypersonic flows, and kinetic gas dynamic approaches related to the direct simulation Monte Carlo method. She has been a member of the AIAA Plasmadynamics and Lasers Technical Committee since 1994 and is a past-chair. She is a Fellow of the AIAA, associate editor of the Journal of Thermophysics and Heat Transfer, and has co-authored over 110 archival journal article.
