The Fluid Dynamics program supports fundamental engineering research and education on mechanisms and phenomena governing fluid flow from the molecular to the macroscopic scale. Proposed research should contribute to basic understanding of fluid flow phenomena, thus enabling the better design, predictability, efficiency, and control of systems that involve fluids. Areas of emphasis are proposals that address the behavior of new fluid materials and innovative uses of fluids in manufacturing, energy and the environment, materials development, biotechnology, nanotechnology, sensor development, clinical diagnostics and drug delivery. While the research should focus on fundamentals, a clear connection to potential applications with significant societal/technological impact should be outlined.
Major areas of interest and activity in the program include:
· Bio-inspired Fluid Mechanics and Bio-flows: biomimetics; intracellular flows; fluid-structure interactions; hemodynamics; swimmers; insect flight; fins; biological flow processes; flows in biomedical devices; drug delivery.
· Flow of Complex Fluids: non-Newtonian fluid mechanics; viscoelasticity; flow of polymer solutions and melts; gelation; flow-induced structuring; DNA dynamics; new fluid materials.
· Micro- and Nano-fluidics: micro-and nano-scale flow phenomena; biomedical microdevices; effects of nano-inclusions on rheological properties; molecular dynamics simulations; optofluidics.
· Turbulence and Transition: theory; high Reynolds number experiments; large eddy simulation; direct numerical simulation; transition to turbulence; 3-D boundary layers; multi-phase turbulent flows; flow control and drag reduction.
· Interfacial Interactions and Instabilities: hydrodynamic stability; gas-liquid interfaces; splashing; jetting; droplet interactions; atomization; wetting.
· Instrumentation and Flow Diagnostics: Instrument development; MEMS; shear stress sensors; novel flow imaging; velocimetry.
Proposals on wind and ocean energy harvesting and on environmental flows could be submitted to the program when the proposed research is focused on fundamental fluid dynamics phenomena or on the development of novel computational fluid dynamics approaches, rather than applications or devices and materials.
Innovative proposals outside of these specific interest areas may be considered. However, prior to submission, it is recommended that the PI contact the Program Director to avoid the possibility of the proposal being returned without review.
The duration of unsolicited awards is generally one to three years. The typical award size for the program is around $90,000 per year. Proposals requesting a substantially higher amount than this, without prior consultation with the Program Director, may be returned without review. Small equipment proposals of less than $100,000 will also be considered and may be submitted during the annual proposal submission window.
