Learning Efficient Navigation in Vortical Flow Fields

no code implementations21 Feb 2021 Peter Gunnarson, Ioannis Mandralis, Guido Novati, Petros Koumoutsakos, John O. Dabiri

Efficient point-to-point navigation in the presence of a background flow field is important for robotic applications such as ocean surveying.

A single-camera, 3D scanning velocimetry system for quantifying active particle aggregations

no code implementations11 Feb 2021 Matt K. Fu, Isabel A. Houghton, John O. Dabiri

A three-dimensional (3D) scanning velocimetry system is developed to quantify the 3D configurations of particles and their surrounding volumetric, three-component velocity fields.

Model parameter estimation using coherent structure coloring

no code implementations31 Oct 2018 Kristy L. Schlueter-Kuck, John O. Dabiri

We propose to instead use error in the coherent structure coloring (CSC) field to assess model skill.

Simultaneous Coherent Structure Coloring facilitates interpretable clustering of scientific data by amplifying dissimilarity

1 code implementation12 Jul 2018 Brooke E. Husic, Kristy L. Schlueter-Kuck, John O. Dabiri

sCSC performs a sequence of binary splittings on the dataset such that the most dissimilar data points are required to be in separate clusters.

Identification of individual coherent sets associated with flow trajectories using Coherent Structure Coloring

no code implementations18 Aug 2017 Kristy L. Schlueter-Kuck, John O. Dabiri

We present a method for identifying the coherent structures associated with individual Lagrangian flow trajectories even where only sparse particle trajectory data is available.

Coherent structure coloring: identification of coherent structures from sparse data using graph theory

no code implementations1 Oct 2016 Kristy L. Schlueter-Kuck, John O. Dabiri

We present a frame-invariant method for detecting coherent structures from Lagrangian flow trajectories that can be sparse in number, as is the case in many fluid mechanics applications of practical interest.
