Aerodynamics and Aeroacoustics of da Vinci's Aerial Screw
Suryansh Prakhar, Jung-Hee Seo, Rajat Mittal
Leonardo da Vinci's aerial screw, conceived in the 15th century, represents one of the earliest conceptualizations of lift-generating rotary flight. Despite its historical signific…
From vortices to forces - a data-driven framework for unsteady lift generation in three-dimensional vortex-dominated flows
Suryansh Prakhar, Jung-Hee Seo, Rajat Mittal
Time-varying flow-induced forces on bodies immersed in fluid flows play a key role across a range of natural and engineered systems, from biological locomotion to propulsion and en…
Bioinspired Drone Rotors for Reduced Aeroacoustic Noise and Improved Efficiency
Suryansh Prakhar, Jung-Hee Seo, Rajat Mittal
The application of unmanned aerial vehicles (UAVs) is surging across several industries, paralleled by growing demand for these UAVs. However, the noise emitted by UAVs remains a s…
Modal Force Partitioning -- A Method for Determining the Aerodynamic Loads for Decomposed Flow Modes with Application to Aeroacoustic Noise
Suryansh Prakhar, Jung-Hee Seo, Rajat Mittal
Aerodynamic loads play a central role in many fluid dynamics applications, and we present a method for identifying the structures (or modes) in a flow that make dominant contributi…
