This National Science Foundation (NSF) Engineering (CFDA 47.041) Project Grant award to Portland State University (PSU) totaling $330,669 will develop and apply novel computational and experimental tools to study complex fluid dynamics interactions between floating wind turbine wakes, prevailing winds, and ocean waves. Key goals include: (i) Developing improved surface flux parameterizations for large eddy simulations (LES) of the marine boundary layer above ocean waves, using a...
This Project Grant award from the National Science Foundation's (NSF) Engineering program (CFDA 47.041) aims to advance the understanding of pulsatile turbulent flows over rough surfaces and develop new predictive tools for these complex flow phenomena. The $154,994 award, which runs from December 1, 2024 to November 30, 2029, will fund high-resolution simulations, novel statistical analyses, and physics-based modeling to characterize the temporal and spatial coherence of turbulent boundary...
The National Science Foundation awarded The Pennsylvania State University a $363,304 Project Grant under the Engineering (47.041) federal grant program. The award will support research towards developing a universal roughness model for fluid flows over complex boundaries from June 15, 2022 to August 31, 2023. The research aims to establish a new computational framework based on space/time averaging of the Navier-Stokes equations to accurately model fluid flows over a wide range of rough...
This three-year, $395,999 Project Grant from the National Science Foundation Division of Chemical, Bioengineering, Environmental, and Transport Systems Engineering program will fund research at Portland State University to disentangle inertial particle-turbulence mechanisms in microgravity conditions. The University will perform experimental exploration of single and collective particle interactions with turbulence using the Dryden Drop Tower facility. Objectives include dissociating the effects...
This Project Grant award of $815,736 from the National Science Foundation's Engineering program (CFDA 47.041) supports research at Virginia Polytechnic Institute & State University (Virginia Tech) to study non-equilibrium rough wall boundary layers. The project will compare the properties and mechanics of boundary layers generated over two- and three-dimensional rough walls with the same effective sand-grain roughness. This research aims to reveal the limits and mechanisms of rough wall...
This Project Grant award from the National Science Foundation (NSF) under the Engineering program (CFDA 47.041) provides $549,999 to Cleveland State University (CSU) to improve understanding of urban microclimate (UMC) dynamics and their interactions with urban morphology, natural heat sources, and anthropogenic activities. The research aims to characterize and parameterize UMC dynamics, quantify multi-scale interactions between UMC dynamics and building characteristics, and advance...
This National Science Foundation (NSF) Project Grant award under CFDA 47.041 (Engineering) provides $490,525.00 to The Regents of the University of Minnesota, doing business as the Office of Sponsored Projects Administration, to conduct research on stochastic modeling of turbulence over rough surfaces.
