Time-Symmetry of Lagrangian Coherent Structures in Active Turbulence
Suvarchalanjan Bellaganti, Amal Manoharan, Kirti Kashyap +1
Active flows are central to mixing and transport across living systems. While Newtonian fluids remain laminar, diffusive and predictable at the microscale, living fluids like dense…
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.…
Topological entropy of stationary three-dimensional turbulence
Ankan Biswas, Amal Manoharan, Ashwin Joy
Topological entropy serves as a viable candidate for quantifying mixing and complexity of a highly chaotic system. Particularly in turbulence, this is determined as the exponential…
Topological Entropy of Two Dimensional Turbulence
Amal Manoharan, Sai Subramanian, Ashwin Joy
Deformation of material lines drives transport and dissipation in many industrial and natural flows. Here we report an exact Eulerian formula for the stretching rate of a material…
Persistence in Active Turbulence
Amal Manoharan, Sanjay CP, Ashwin Joy
Active fluids such as bacterial swarms, self-propelled colloids, and cell tissues can all display complex spatio-temporal vortices that are reminiscent of inertial turbulence. This…
