Obstacle-aware navigation of smart microswimmers in a turbulent flow
Vaishnavi Gajendragad, Akanksha Gupta, Nadia Bihari Padhan +1
Microswimmers in turbulent flows often navigate complex, heterogeneous, and obstacle-rich environments, where they exhibit intricate behaviors such as trapping at and escape from o…

Intermittency and non-universality of pair dispersion in isothermal compressible turbulence
Sadhitro De, Dhrubaditya Mitra, Rahul Pandit
Statistical properties of the pair dispersion of Lagrangian particles (tracers) in incompressible turbulent flows provide insights into transport and mixing. We explore the same in…

Uncovering the multifractality of Lagrangian pair dispersion in shock-dominated turbulence
Sadhitro De, Dhrubaditya Mitra, Rahul Pandit
Lagrangian pair dispersion provides insights into mixing in turbulent flows. By direct numerical simulations (DNS) we show that the statistics of pair dispersion in the randomly fo…
