Turbulence is ineffective in causing raindrop growth in polluted clouds
K. Shri Vignesh, Ambedkar Sanket Sukdeo, P. V. Sruthibhai +8
Aerosol-cloud interactions represent the largest uncertainty in climate-change assessment, and while cloud turbulence is considered crucial for droplet growth, its precise role rem…
Streak generation in viscosity-stratified wall-bounded flows
Anagha Madhusudanan, Simon J. Illingworth, Rama Govindarajan
Streamwise elongated flow structures, or streaks, dominate wall-bounded flows. We show that the renowned lift-up mechanism, that generates streaks, is significantly altered by visc…
Solla: Towards a Speech-Oriented LLM That Hears Acoustic Context
Junyi Ao, Dekun Chen, Xiaohai Tian +6
Large Language Models (LLMs) have recently shown remarkable ability to process not only text but also multimodal inputs such as speech and audio. However, most existing models prim…
Emergence of capillary waves in miscible co-flowing fluids
Alessandro Carbonaro, Giovanni Savorana, Luca Cipelletti +2
We show that capillary waves can exist at the the boundary between miscible co-flowing fluids. We unveil that the interplay between transient interfacial stresses and confinement d…
Mechanism of instability in non-uniform dusty channel flow
Anup Kumar, Rama Govindarajan
Particles in pressure-driven channel flow are often inhomogeneously distributed. Two modes of low-Reynolds number instability, absent in Poiseuille flow of clean fluid, are created…
