<p>This video will showcase the research efforts and capabilities of the Flow Simulation Research Group at the University of Virginia, led by Dr. Haibo Dong. The research done by the group focuses on computational modeling of biological flows with an emphasis on garnering advantageous methods of locomotion to be leveraged in engineering design. A large part of our work as a research group is applying the information gathered from biological examples and applying it to air and hydro vehicles. The video will include footage of the setup used in the lab to capture high-speed videos of biological flight, along with example videos of dragonfly, butterfly, and damselfly flight. This setup consists of a system of high frame rate cameras, allowing the development of video footage which is then used to generate geometries and kinematics for fluid dynamics models. These videos will be shown along with the computational fluid dynamics models that were generated using the data gathered from the flight videos and from an in-house immersed boundary method-based incompressible flow solver. In this solver, the Navier-Stokes’s equations are solved using a finite difference-based immersed boundary method on Cartesian grids. Flow visualization is then used to analyze the vortex dynamics and flow physics associated with the flight. Along with these flying examples, a demonstration of the application to swimming research and medical research will also be included. This will comprise of biological models of trout, tuna, dolphin, and jackfish generated from video data contributed by other laboratories and flapping uvula used to study obstructive sleep apnea.</p>

ASME 2021 Fluids Engineering Division Summer Meeting (FEDSM2021)

Supporting the need among researchers worldwide for additional online and multimedia content, ASME now offers the ASME Conference Video Collection. This platform will collect and provide long-term access to conference presentation videos, encompassing all technology areas within ASME's technical conference and events program. About 30,000-40,000 engineers across all mechanical engineering and related disciplines participate in ASME conferences each year. This includes authors of approximately 6,000 to 8,000 technical papers published by ASME, the majority of whom also submit video presentations for our virtual conferences. The video collection will be available as an add-on to existing product packages or as a separate subscription.
