Abstract Flows in nature and in engineering are often complex, forced by external agents, boundary stresses, and internal instabilities, and pervaded by multiscale structures such as eddies, plumes, jets, waves, and turbulence, spanning many orders of magnitude in size. The nonlinear nature of the dynamics implies a coupling between these multiple scales, which often plays a major role in determining mean-flow evolution and is a primary factor limiting our predictive modeling capabilities. To tackle this class of problems, I will present a scale-analysis framework we have been developing that is rooted in commonly used techniques in the subjects of PDEs and Large Eddy Simulation modeling. The approach relies on a synergistic interplay between rigorous mathematics, physical insight, and numerical computations to probe large data sets from simulations, satellite observations, and experimental measurements. I will discuss applications to flows in high-energy-density plasmas and the global ocean circulation. |

Biography Hussein is currently an Associate Professor in the Hajim School of Engineering at the University of Rochester, where he is a faculty member of the Mechanical Engineering Department, the Institute for Matter at Extreme Energy Density, and the Center for Energy and Environment. He is also a Staff Scientist at the DOE Laboratory for Laser Energetics at UofR. In 2021, he was elected as vice-chair of the Group on the Physics of Climate within the American Physical Society. He is currently serving as chair-elect for 2022, and will become chair in 2023. Prior to UofR, he held a postdoctoral appointment in the Center for Nonlinear Studies at Los Alamos National Laboratory. He earned his PhD from Johns Hopkins University and his BSc from the American University of Beirut. His research has been supported by NSF, DOE, NNSA, and NASA, and was awarded the DOE Early CAREER Award in 2019. His Complex Flow group is diverse both in the composition of its members and in its research, which has appeared in cross-disciplinary journals, including Nature, Science Advances, Physical Review Letters, as well as in disciplinary journals of fluid mechanics, oceanography, plasma physics, applied mathematics, and astrophysics. Hussein was born in Beirut, Lebanon and enjoys outdoor sports activities in their many forms, live music, and swing dancing. |
