Liquid velocity fluctuations and energy spectra in three-dimensional buoyancy driven bubbly flows
Vikash Pandey, Rashmi Ramadugu, Prasad Perlekar
We present a direct numerical simulation (DNS) study of pseudo-turbulence in buoyancy driven bubbly flows for a range of Reynolds ($\Rey$) and Atwood ($\At$) numbers. We study the…
Fixation in Competing Populations: Diffusion and Strategies for Survival
Tapas Singha, Prasad Perlekar, Mustansir Barma
How should dispersal strategies be chosen to increase the likelihood of survival of a species? We obtain the answer for the spatially extended versions of three well-known models o…
Inertia drives a flocking phase transition in viscous active fluids
Rayan Chatterjee, Navdeep Rana, R. Aditi Simha +2
How fast must an oriented collection of extensile swimmers swim to escape the instability of viscous active suspensions? We show that the answer lies in the dimensionless combinati…
Clustering and energy spectra in two-dimensional dusty gas turbulence
Vikash Pandey, Dhrubaditya Mitra, Prasad Perlekar
We present Direct Numerical Simulation (DNS) of heavy inertial particles (dust) immersed in two-dimensional turbulent flow (gas). The dust are modeled as mono-dispersed heavy parti…
