Hydrodynamics of Flapping Foils Undergoing Irregular Motion with Application to Wave-Assisted Propulsion
Harshal S. Raut, Jung-Hee Seo, Rajat Mittal
Flapping foils are widely studied as bioinspired propulsors, yet most investigations have focused on regular, sinusoidal kinematics. In realistic environments, however, irregular m…
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…
Scaling Laws for Caudal Fin Swimmers Incorporating Hydrodynamics, Kinematics, Morphology, and Scale Effects
Jung Hee Seo, Ji Zhou, Rajat Mittal
Many species of fish, as well as biorobotic underwater vehicles, employ body caudal fin propulsion, in which a wave-like body motion culminates in high-amplitude caudal fin oscilla…
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…
A GPU-Accelerated Sharp Interface Immersed Boundary Solver for Large Scale Flow Simulations
Sushrut Kumar, Joshua Romero, Jung-Hee Seo +2
Immersed boundary methods (IBMs) facilitate the simulation of flows around stationary, moving, and deforming bodies on Cartesian grids. However, extending these simulations to the…
Harnessing Leading-Edge Vortices for Improved Thrust Performance of Wave-Induced Flapping Foil Propulsors
Harshal S. Raut, Jung-Hee Seo, Rajat Mittal
This study employs high-fidelity fluid-structure interaction simulations to investigate design optimizations for wave-assisted propulsion (WAP) systems using flapping foils. Buildi…
