Binary-Fluid Turbulence: Signatures of Multifractal Droplet Dynamics and Dissipation Reduction
Nairita Pal, Prasad Perlekar, Anupam Gupta +1
We present an extensive direct numerical simulation of statistically steady, homogeneous, isotropic turbulence in two-dimensional, binary-fluid mixtures with air-drag-induced frict…
Two-dimensional Turbulence in Symmetric Binary-Fluid Mixtures: Coarsening Arrest by the Inverse Cascade
Prasad Perlekar, Nairita Pal, Rahul Pandit
We study two-dimensional (2D) binary-fluid turbulence by carrying out an extensive direct numerical simulation (DNS) of the forced, statistically steady turbulence in the coupled C…
Dynamics of circular arrangements of vorticity in two dimensions
Rohith V. Swaminathan, S. Ravichandran, Prasad Perlekar +1
The merger of two like-signed vortices is a well-studied problem, but in a turbulent flow, we may often have more than two like-signed vortices interacting. We study the merger of…
On the Peterlin approximation for turbulent flows of polymer solutions
Dario Vincenzi, Prasad Perlekar, Luca Biferale +1
We study the impact of the Peterlin approximation on the statistics of the end-to-end separation of poly- mers in a turbulent flow. The FENE and FENE-P models are numerically integ…
Inertial particle acceleration in strained turbulence
Chung-min Lee, Ármann Gylfason, Prasad Perlekar +1
The dynamics of inertial particles in turbulence is modelled and investigated by means of direct numerical simulation of an axisymmetrically expanding homogeneous turbulent straine…
