The global attractor of the Toner-Tu-Swift-Hohenberg equations of active turbulence and its properties
Daniel W. Boutros, Kolluru Venkata Kiran, John D. Gibbon +1
The Toner-Tu-Swift-Hohenberg (TTSH) equations are one of the basic equations that are used to model turbulent behaviour in active matter, specifically the swarming of bacteria in s…
Emergence of Local Ordering and Mesoscale Giant Number Fluctuations in Active Turbulence
Kirti Kashyap, Kolluru Venkata Kiran, Anupam Gupta
We study spatiotemporal chaos in two-dimensional dense active suspensions using a generalized hydrodynamic model. Increasing activity induces a structural transition marked by the…
Onset of Intermittency and Multiscaling in Active Turbulence
Kolluru Venkata Kiran, Kunal Kumar, Anupam Gupta +2
Recent results suggest that highly active, chaotic, non-equilibrium states of living fluids might share much in common with high Reynolds number, inertial turbulence. We now show,…
Turbulent cascade arrests and the formation of intermediate-scale condensates
Kolluru Venkata Kiran, Dario Vincenzi, Rahul Pandit
Energy cascades lie at the heart of the dynamics of turbulent flows. In a recent study of turbulence in fluids with odd-viscosity [de Wit \textit{et al.}, Nature \textbf{627}, 515…
Novel turbulence and coarsening arrest in active-scalar fluids
Nadia Bihari Padhan, Kolluru Venkata Kiran, Rahul Pandit
We uncover a new type of turbulence -- activity-induced homogeneous and isotropic turbulence in a model that has been employed to investigate motility-induced phase separation (MIP…
An analytical and computational study of the incompressible Toner-Tu Equations
John. D. Gibbon, Kolluru Venkata Kiran, Nadia Bihari Padhan +1
The incompressible Toner-Tu (ITT) partial differential equations (PDEs) are an important example of a set of active-fluid PDEs. While they share certain properties with the Navier-…
