Estimates for the 2D Navier-Stokes equations: the effects of forcing
Ritwik Mukherjee, John D. Gibbon, Dario Vincenzi
Mathematical estimates for the Navier-Stokes equations are traditionally expressed in terms of the Grashof number, which is a dimensionless measure of the magnitude of the forcing…
Geometric Intermittency in Turbulence
Ritwik Mukherjee, Siddhartha Mukherjee, I. V. Kolokolov +3
Equal-time scaling exponents in fully developed turbulence typically exhibit non anomalous scaling in the inverse cascade of two-dimensional (2D) turbulence and anomalous scaling i…
Hydrodynamics of a hard-core active lattice gas
Ritwik Mukherjee, Soumyabrata Saha, Tridib Sadhu +2
We present a fluctuating hydrodynamic description of an active lattice gas model with excluded volume interactions that exhibits motility-induced phase separation under appropriate…
Extreme dynamics and relaxation of quantum gases: A hydrodynamic approach
Ritwik Mukherjee, Abhishek Dhar, Manas Kulkarni +1
The evolution of quantum gases, released from traps, are studied through hydrodynamics, both analytically and numerically, in one and two dimensions. In particular, we demonstrate…
Intermittent fluctuations determine the nature of chaos in turbulence
Aikya Banerjee, Ritwik Mukherjee, Sugan Durai Murugan +2
We adapt recent ideas for many-body chaos in nonlinear, Hamiltonian fluids [Murugan \textit{et al.}, Phys. Rev. Lett. 127, 124501 (2021)] to revisit the question of the Reynolds nu…
