Liquid-Droplet Coalescence: CNN-based Reconstruction of Flow Fields from Concentration Fields
Vasanth Kumar Babu, Nadia Bihari Padhan, Rahul Pandit
Liquid-droplet coalescence and the mergers of liquid lenses are problems of great practical and theoretical interest in fluid dynamics and the statistical mechanics of multi-phase…
Interfaces as transport barriers in two-dimensional Cahn-Hilliard-Navier-Stokes turbulence
Nadia Bihari Padhan, Rahul Pandit
We investigate the role of interfaces as transport barriers in binary-fluid turbulence by employing Lagrangian tracer particles. The Cahn-Hilliard-Navier-Stokes (CHNS) system of pa…
Novel turbulence and coarsening arrest in active-scalar fluids
Nadia Bihari Padhan, Kolluru Venkata Kiran, Rahul Pandit
We uncover a new type of turbulence -- activity-induced homogeneous and isotropic turbulence in a model that has been employed to investigate motility-induced phase separation (MIP…
Unveiling the Spatiotemporal Evolution of Liquid-Lens Coalescence: Self-Similarity, Vortex Quadrupoles, and Turbulence in a Three-Phase Fluid System
Nadia Bihari Padhan, Rahul Pandit
We demonstrate that the three-phase Cahn-Hilliard-Navier-Stokes (CHNS3) system provides a natural theoretical framework for studying liquid-lens coalescence, which has been investi…
