What the grant funds

The Fluid Dynamics program is part of the Transport Phenomena cluster, which also includes 1) the Combustion and Fire Systems program; 2) the Particulate and Multiphase Processes program; and 3) the Thermal Transport Processes program. The Fluid Dynamics program supports fundamental research toward gaining an understanding of the physics of various fluid dynamics phenomena. Proposed research should contribute to basic scientific understanding via experiments, theoretical developments, and computational discovery. Major areas of interest and activity in the program include: Turbulence and transition: High Reynolds number experiments; large eddy simulation; direct numerical simulation; transition to turbulence; 3-D boundary layers; separated flows; multi-phase turbulent flows; flow control and drag reduction. High-speed boundary layer transition and turbulence at Mach numbers greater than 5 to understand modal and/or non-modal interactions leading to boundary layer transition and the ensuing developing and fully developed turbulent boundary layer flows. Combined experiments and simulations are encouraged. Bio-fluid physics: Bio-inspired flows; biological flows with emphasis on flow physics. Non-Newtonian fluid mechanics: Single-phase viscoelastic flows; solutions of macro-molecules. Bubble dynamics: Bubbles related to cavitation and/or drag reduction or impacting the fluid viscosity (locally) or manipulation of bubbles with external excitation (acoustofluidics). Microfluidics and nanofluidics: Micro-and nano-scale flow physics. Wind and ocean energy harvesting: Focused on fundamental fluid dynamics associated with renewable energy. The NSF-DOE (Department of Energy) joint funding area is focused on high Reynolds number aerodynamics of thick airfoils (> 21% thickness/chord) operating in complex (3D) steady, unsteady, and separated flows. Impacts of blade surface quality/roughness rotor performance on the aerodynamic/aeroelastic performance of novel rotor geometries and supporting structures are also of interest. Air/sea interactions, including waves/currents, on the hydrodynamic loading for offshore wind turbines. Improved measurement techniques and sensing/control technologies required to characterize the metocean environment impact on performance. The DoE participates in this initiative through the Wind Energy Technologies Office (program manager Michael Derby, email: michael.derby@ee.doe.gov).
