Numerical Simulation of Inertia-Dominated Turbulent Flows Dr. William Anderson May 10, 2018 2:00 pm/NWC 560 Abstract: This talk presents a summary of three active research themes: (1) canonical wall-bounded turbulence and roughness effects; (2) aeolian processes on Earth and Mars; and (3) small-scale mixing in the ocean-mixed layer. On the first: turbulent flows respond to […]
Abstract: Understanding flows within the urban canopy layer is crucial for determining the distribution of particulate matter in urban areas and implications for air quality and human health. While multiple studies have been conducted to understand plume characteristics in urban environments, plume behavior close to point sources (< 1 km) and the effects of buildings and foliage on plume characteristics are not well understood.
Recent Advances and Applications of Utilizing Unmanned Aircraft Systems for Atmospheric Research Boundary Layer, Urban Meteorology, and Land-Surface Processes Brian Greene April 19, 2019 2:00pm/ NWC 5600 Abstract: In recent years, the commercial accessibility of unmanned aircraft systems (UAS) and miniaturized sensor payloads have increased significantly, making it feasible to sample and characterize the planetary […]
At the WHAM laboratory, we have been simulating the tornadic wind fields numerically (using CFD simulations) and experimentally (in laboratory tornado simulators) to study the static and dynamic responses on civil structures induced by tornadoes. We believe that the entire community has a role to play in improving their communityâ€™s resilience to tornadoes. To achieve true tornado resilience, besides technical advancements, the whole community should be aware of the threats and, following best practices, act appropriately together.
