Interface Fluctuations in a Turbulent Binary Fluid using Data-Driven Methods
Samuel Z Khiangte, Triparna Sanyal, Sumantra Sarkar +1
Interfacial fluctuations in a two-phase binary fluid mixture reveal signatures of underlying physical processes that occur within each phase and on a range of spatial and temporal…
REV-INR: Regularized Evidential Implicit Neural Representation for Uncertainty-Aware Volume Visualization
Shanu Saklani, Tushar M. Athawale, Nairita Pal +3
Applications of Implicit Neural Representations (INRs) have emerged as a promising deep learning approach for compactly representing large volumetric datasets. These models can act…
Ephemeral Antibubbles: Spatiotemporal Evolution from Direct Numerical Simulations
Nairita Pal, Rashmi Ramadugu, Prasad Perlekar +1
Antibubbles, which consist of a shell of a low-density fluid inside a high-density fluid, have several promising applications. We show, via extensive direct numerical simulations (…
Local Wave Number Model for Inhomogeneous Two-Fluid Mixing
Nairita Pal, Ismael Boureima, Noah Braun +3
We present a study of a two-point spectral turbulence model (Local Wave-Number model or LWN model) for the Rayleigh-Taylor (RT) instability. The model outcomes are compared with st…
Preferential Sampling of Elastic Chains in Turbulent Flows
Jason R. Picardo, Dario Vincenzi, Nairita Pal +1
A string of tracers, interacting elastically, in a turbulent flow is shown to have a dramatically different behaviour when compared to the non-interacting case. In particular, such…
Two-point spectral model for variable-density homogeneous turbulence
Nairita Pal, Susan Kurien, Timothy Clark +2
We present a study of buoyancy-driven variable-density homogeneous turbulence, using a two-point spectral closure model. We compute the time-evolution of the spectral distribution…
Exotic Multifractal Conductance Fluctuations in Graphene
Kazi Rafsanjani Amin, Samriddhi Sankar Ray, Nairita Pal +2
In quantum systems, signatures of multifractality are rare. They have been found only in the multiscaling of eigenfunctions at critical points. Here we demonstrate multifractality…
The role of BKM-type theorems in Euler, Navier-Stokes and Cahn-Hilliard-Navier-Stokes analysis
John D. Gibbon, Anupam Gupta, Nairita Pal +1
The Beale-Kato-Majda theorem contains a single criterion that controls the behaviour of solutions of the incompressible Euler equations. Versions of this theorem are discussed…
A regularity criterion for solutions of the three-dimensional Cahn-Hilliard-Navier-Stokes equations and associated computations
John D. Gibbon, Nairita Pal, Anupam Gupta +1
We consider the 3D Cahn-Hilliard equations coupled to, and driven by, the forced, incompressible 3D Navier-Stokes equations. The combination, known as the Cahn-Hilliard-Navier-Stok…
Binary-Fluid Turbulence: Signatures of Multifractal Droplet Dynamics and Dissipation Reduction
Nairita Pal, Prasad Perlekar, Anupam Gupta +1
We present an extensive direct numerical simulation of statistically steady, homogeneous, isotropic turbulence in two-dimensional, binary-fluid mixtures with air-drag-induced frict…
Two-dimensional Turbulence in Symmetric Binary-Fluid Mixtures: Coarsening Arrest by the Inverse Cascade
Prasad Perlekar, Nairita Pal, Rahul Pandit
We study two-dimensional (2D) binary-fluid turbulence by carrying out an extensive direct numerical simulation (DNS) of the forced, statistically steady turbulence in the coupled C…
