SUMMARY:A General Framework to Analyzing Multi-Scale Complex Flows: Ap
 plications to Oceanic\, Plasma\, and Compressible Flows\, Plasma Physi
 cs (Physics/ECE/NE 922) Seminar\, Prof. Hussein Aluie\, University of 
 Rochester
DESCRIPTION:Flows in nature and in engineering are often complex\, for
 ced by external agents\, boundary stresses\, and internal instabilitie
 s\, and pervaded by multiscale structures such as eddies\, plumes\, je
 ts\, waves\, and turbulence --spanning many orders of magnitude in siz
 e. The nonlinear nature of the dynamics implies a coupling between the
 se multiple scales\, which often plays a major role in determining mea
 n-flow evolution and is a primary factor limiting our predictive model
 ing capabilities. To tackle this class of problems in fluid dynamics\,
  I will present a scale-analysis framework we have been developing tha
 t is rooted in commonly used techniques in the subjects of PDEs and La
 rge Eddy Simulation modeling (LES). The approach is very general and a
 llows for resolving nonlinear processes at any scale and at any locati
 on in the flow. It relies on a synergistic interplay between rigorous 
 mathematics\, physical insight\, and numerical computations to probe l
 arge data sets from simulations\, satellite observations\, and experim
 ental measurements. I will discuss the application of this methodology
  to oceanic\, plasma\, and compressible flows.
