Learning Optimal Parametric Hydrodynamic Database for Vortex-Induced Crossflow Vibration Prediction
Samuel Rudy, Dixia Fan, Jose del Aguila Ferrandis +2
The Vortex-induced vibration (VIV) prediction of long flexible cylindrical structures relies on the accuracy of the hydrodynamic database constructed via rigid cylinder forced vibr…
A fast multi-fidelity method with uncertainty quantification for complex data correlations: Application to vortex-induced vibrations of marine risers
Xuhui Meng, Zhicheng Wang, Dixia Fan +2
We develop a fast multi-fidelity modeling method for very complex correlations between high- and low-fidelity data by working in modal space to extract the proper correlation funct…
Reinforcement Learning for Active Flow Control in Experiments
Dixia Fan, Liu Yang, Michael S Triantafyllou +1
We demonstrate experimentally the feasibility of applying reinforcement learning (RL) in flow control problems by automatically discovering active control strategies without any pr…
Deep Learning of Vortex Induced Vibrations
Maziar Raissi, Zhicheng Wang, Michael S. Triantafyllou +1
Vortex induced vibrations of bluff bodies occur when the vortex shedding frequency is close to the natural frequency of the structure. Of interest is the prediction of the lift and…
Optimal undulating swimming for a single fish-like body and for a pair of interacting swimmers
Audrey P. Maertens, Amy Gao, Michael S. Triantafyllou
We establish through numerical simulation conditions for optimal undulatory propulsion for a single fish, and for a pair of hydrodynamically interacting fish, accounting for linear…
Artificial ciliary bundles with nano fiber tip links
Mohsen Asadnia, Ajay Giri Prakash Kottapalli, Jianmin Miao +1
Mechanosensory ciliary bundles in fishes are the inspiration for carefully engineered artificial flow sensors. We report the development of a new class of ultrasensitive MEMS flow…
Exquisitely sensitive seal whisker-like sensors detect wakes at large distances
Heather R. Beem, Michael S. Triantafyllou
Blindfolded harbor seals are able to use their uniquely shaped whiskers to track vortex wakes left by moving animals and objects that passed by up to 30 seconds earlier; this is an…
A Novel Degree of Freedom in Flapping Wings Shows Promise for a Dual Aerial/Aquatic Vehicle Propulsor
Jacob S. Izraelevitz, Michael S. Triantafyllou
Ocean sampling for highly temporal phenomena, such as harmful algal blooms, necessitates a vehicle capable of fast aerial travel interspersed with an aquatic means of acquiring in-…
Ultra-fast escape maneuver of an octopus-inspired robot
G. D. Weymouth, V. Subramaniam, M. S. Triantafyllou
We design and test an octopus-inspired flexible hull robot that demonstrates outstanding fast-starting performance. The robot is hyper-inflated with water, and then rapidly deflate…
Efficiency of Fish Propulsion
A. P. Maertens, M. S. Triantafyllou, D. K. P. Yue
It is shown that the system efficiency of a self-propelled flexible body is ill-defined unless one considers the concept of quasi-propulsive efficiency, defined as the ratio of the…
