Dynamics of a long chain in turbulent flows: Impact of vortices
Jason R. Picardo, Rahul Singh, Samriddhi Sankar Ray +1
We show and explain how a long bead-spring chain, immersed in a homogeneous, isotropic turbulent flow, preferentially samples vortical flow structures. We begin with an elastic, ex…
Bridging Inertial and Dissipation Range Statistics in Rotating Turbulence
Shailendra K. Rathor, Manohar Kumar Sharma, Samriddhi Sankar Ray +1
We investigate the connection between the inertial range and the dissipation range statistics of rotating turbulence through detailed simulations of a helical shell model and a mul…
Elasto-inertial Chains in a Two-dimensional Turbulent Flow
Rahul Singh, Mohit Gupta, Jason R. Picardo +2
The interplay of inertia and elasticity is shown to have a significant impact on the transport of filamentary objects, modelled by bead-spring chains, in a two-dimensional turbulen…
Lagrangian Irreversibility and Eulerian Dissipation in Fully-Developed Turbulence
Jason R. Picardo, Akshay Bhatnagar, Samriddhi Sankar Ray
We revisit the issue of Lagrangian irreversibility in the context of recent results [Xu, et al., PNAS, 111, 7558 (2014)] on flight-crash events in turbulent flows and show how extr…
Statistics of Lagrangian Trajectories in a Rotating Turbulent Flow
Priyanka Maity, Rama Govindarajan, Samriddhi Sankar Ray
We investigate the Lagrangian statistics of three-dimensional rotating turbulent flows through direct numerical simulations. We find that the emergence of coherent vortical structu…
