Capturing Turbulent Dynamics and Statistics in Experiments with Unstable Periodic Orbits
Balachandra Suri, Logan Kageorge, Roman O. Grigoriev +1
In laboratory studies and numerical simulations, we observe clear signatures of unstable time-periodic solutions in a moderately turbulent quasi-two-dimensional flow. We validate t…
Heteroclinic and Homoclinic Connections in a Kolmogorov-Like Flow
Balachandra Suri, Ravi Kumar Pallantla, Michael F. Schatz +1
Recent studies suggest that unstable recurrent solutions of the Navier-Stokes equation provide new insights into dynamics of turbulent flows. In this study, we compute an extensive…
Unstable Equilibria and Invariant Manifolds in Quasi-Two-Dimensional Kolmogorov-like Flow
Balachandra Suri, Jeffrey Tithof, Roman O. Grigoriev +1
Recent studies suggest that unstable, non-chaotic solutions of the Navier-Stokes equation may provide deep insights into fluid turbulence. In this article, we present a combined ex…
