Deconstructing wall turbulence - visualization of resolvent modes

We report on the outcome of a design-informed visualization project performed by the Caltech/JPL/Art Center Data Visualization Summer Internship Program tasked with creating a visualization of the deconstruction of a full turbulent flow field into subsets of dynamic, interacting building blocks. The goal was to create a visualization suite capable of illuminating the velocity fields associated with individual resolvent modes and the rapid increase in complexity associated with linear superposition of modes. The software, named ModeDynamix has the potential to provide insight into the underlying dynamics of wall turbulence.
