Scale-by-scale energy transfers in bubbly flows
Hridey Narula, Vikash Pandey, Dhrubaditya Mitra +1
Buoyancy-driven bubbly flows naturally have spatially-dependent density fields, which allow for multiple definitions of the scale-dependent (or filtered) energy. A priori, it is no…
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…
The broken link between space and time in elastic turbulence
Giulio Foggi Rota, Rahul K. Singh, Alessandro Chiarini +4
Elastic turbulence (ET), observed in flows of sufficiently elastic polymer solution at small inertia, is characterized by chaotic motions and power-law scaling of energy spectrum (…
Vector Differential Operators in arbitrary coordinates: a general approach
Priyabrata Mitra, Dhrubaditya Mitra
We present a method for calculating the results of operation of differential operators operating on components of vector in generalized coordinates not restricted to orthogonal one…
Renormalization group analysis of noisy neural field
Jie Zang, Pascal Helson, Shenquan Liu +2
Neurons in the brain show great diversity in their individual properties and their connections to other neurons. To develop an understanding of how neuronal diversity contributes t…
