This National Science Foundation Project Grant of $243,229 supports the development of new vortex definition and identification methods and software tools at The University of Texas at Arlington through December 2024. Funded by the NSF Division of Chemical, Bioengineering, Environmental, and Transport Systems under the Engineering (47.041) federal grant program, this award will further refine the mathematical definition of local fluid rotation and global vortex structures to be unique,...
The National Science Foundation (NSF) awarded a 3-year, $100,000 Project Grant to the University of California, Merced (UC Merced) under the Mathematical and Physical Sciences program (CFDA 47.049). The grant supports research to better understand how isolated, self-propelled swimmers, such as autonomous underwater vehicles and microorganisms, are transported in unsteady fluid flows. The project will leverage dynamical systems theory to analyze stable and unstable manifolds, invariant tori,...
The Arizona State University was awarded a $200,000 Project Grant from the National Science Foundation Division of Chemical, Bioengineering, Environmental, and Transport Systems to conduct theoretical and numerical investigations of particle-vortex interactions in semi-dilute dusty flows. The three-year award, issued on August 1, 2022, will support research addressing poorly understood vortex dynamics where feedback forces from suspended dust particles lead to distinct growth and pairing...
This $300,000 Project Grant from the National Science Foundation's Division of Mathematical Sciences, under the Mathematical and Physical Sciences federal grant program (CFDA 47.049), will fund research into the dynamics and scattering of vortices and vortex rings. The grantee, New Jersey Institute of Technology, will mathematically investigate phenomena in the interactions of point vortices and vortex rings, including generalized problems of leapfrogging vortices involving three or more...
This Project Grant award of $292,738 from the National Science Foundation's (NSF) Engineering program (CFDA 47.041) supports research to understand the inner structure of leading-edge vortices on swept-back wings and develop theoretical models to explain recent observations. The goal is to create a new paradigm for controlling tailless aircraft configurations by leveraging the periodic liftoff and propagation of these vortices. The research will be conducted by the University of Arizona and...
The National Science Foundation (NSF) awarded a 3-year, $150,000 Project Grant to North Dakota State University (NDSU) under the Integrative Activities (IA) program (CFDA 47.083) to conduct an experimental study on pulsatile helical flow. The primary objectives are to: (1) establish scaling laws for global helicity in pulsatile laminar flow, (2) investigate the influence of flow helicity on turbulence onset thresholds, and (3) explore passive mechanisms for helicity generation and control. The...
