Geometry, elasticity, and activity in the transport of self-propelled filaments in turbulence
Kunal Kumar, Aliv Sahoo, Rahul Kumar Singh +1
We investigate the transport of elastic active filaments in two-dimensional turbulence, focusing on how propulsion geometry and elasticity determine vortex trapping and transport.…
Parity-Dependent Scaling of Velocity-Gradient Correlations in Turbulence
Anwesha Dey, Ritwik Mukherjee, Aikya Banerjee +1
We investigate two-point velocity-gradient correlation functions in homogeneous isotropic turbulence using exact relations and direct numerical simulations. The second-order gradie…
The significance of two-way coupling in two-dimensional, dusty turbulence
Harshit Joshi, Amal Manoharan, Samriddhi Sankar Ray
The significance of small-scale forcing of particles on the carrier two-dimensional turbulent flow has been shown to influence the spectral scaling properties of the carrier fluid.…
Reduction of Triadic Interactions Suppresses Intermittency and Anomalous Dissipation in Turbulence
Anikat Kankaria, Ritwik Mukherjee, Sugan Durai Murugan +2
We investigate how the defining statistical features of three-dimensional turbulence respond to systematic reductions of the Fourier-space triadic interaction network. Using direct…
The dynamics of thermalisation in the Galerkin-truncated, three-dimensional Euler equation
Rajarshi, Mohammad Saif Khan, Prateek Anand +1
The inviscid, partial differential equations of hydrodynamics when projected via a Galerkin-truncation on a finite-dimensional subspace spanning wavenumbers $-{\bf K}_{\rm G} \le {…
Shock trapping and inertial escape: Dust-particle clustering in compressible turbulence
Anikat Kankaria, Samriddhi Sankar Ray
We study the dynamics and clustering of dust particles with inertia in shock-dominated compressible turbulence using the two-dimensional, stochastically forced Burgers equation. At…
