Orientation Dynamics of Gyrotactic Microswimmers in Turbulent Flows
Suraj Kumar Nayak, Vishwanath Shukla, Akshay Bhatnagar
We study the dynamics of gyrotactic microswimmers suspended in homogeneous and isotropic turbulence by using direct numerical simulations (DNS). The swimmers are characterized by t…

Flow-Induced Phase Separation for Active Brownian Particles in Four-Roll-Mill Flow
Soni D. Prajapati, Kusum Seervi, Akshay Bhatnagar +1
We investigate the collective dynamics of active Brownian particles (ABPs) subjected to a steady two-dimensional four-roll-mill flow using numerical simulations. By varying the pac…

Effect of the background flow on the motility induced phase separation
Soni D. Prajapati, Akshay Bhatnagar, Anupam Gupta
We simulate active Brownian particles (ABPs) with soft-repulsive interactions subjected to a four-roll-mill flow. In the absence of flow, this system exhibits motility-induced phas…
