Gappy Reconstruction of Bubbly Flows by Guided Diffusion Models
Hridey Narula, Tianyi Li, Michele Buzzicotti +2
Experiments in multiphase flows are often limited in their ability to simultaneously obtain velocity measurements in different phases. At the same time, flow reconstruction from ph…

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…

Bridging Filtering and Point-Splitting Approaches for Variable-Density Flows
Hridey Narula, Prasad Perlekar
Energy transfer in turbulent flows is typically described either through correlation functions, via the Kármán-Howarth-Monin relation, or through a scale-by-scale budget of the f…
