DESCRIPTION:Prof. Fotis Sotiropoulos\, University of Minnesota\nThe need f
 or restoring degrading waterways coupled with the increasing demand for cl
 ean and renewable energy from wind and water resources have given rise to 
 challenging fluid mechanics problems in the energy-environment nexus.  Sim
 ulation-based research is in many cases the only viable approach for tackl
 ing such problems\, which pose a formidable challenge to even the most adv
 anced numerical methods available today.  Flows of interest take place in 
 arbitrarily complex multi-connected domains with moving\, rigid or flexibl
 e immersed bodies interacting with the flow (fluid/structure interaction)\
 ; involve physical phenomena coupled across disparate scales\; occur over 
 a broad range of Reynolds numbers and flow regimes\; and are dominated by 
 coherent vortical structures.  This talk will present a novel and versatil
 e computational fluid dynamics framework for simulating such flows that in
 tegrates immersed boundary methods with curvilinear\, overset grids\, feat
 ures accurate and robust fluid-structure interaction algorithms\, and is c
 apable of carrying out coherent-structure-resolving simulations of turbule
 nt flows in arbitrarily complex domains with dynamically evolving boundari
 es.  The potential of the method will be demonstrated by discussing applic
 ations to study: 1) the hydrodynamics of aquatic swimming\; 2) turbulent f
 low and transport in natural streams\; and 3) hydrokinetic and wind turbin
 e flows.   Future grand challenges and opportunities for tackling a wide r
 ange of fluid mechanics problems in the energy-environment nexus via simul
 ation-based research will also be discussed.
