Transport of condensing droplets in Taylor-Green vortex flow in the presence of thermal noise
Anu V. S. Nath, Anubhab Roy, Rama Govindarajan +1
We study the role of phase change and thermal noise in particle transport in turbulent flows. We employ a toy model to extract the main physics: condensing droplets are modelled as…
Instability driven by settling and evaporation in a shear flow: a model for asperitas clouds
S. Ravichandran, Rama Govindarajan
We study, by direct numerical simulations in two and three dimensions, the instability caused by the settling and evaporation of water droplets out of a cloudy layer saturated with…
Shapes of a filament on the surface of a bubble
S Ganga Prasath, Joel Marthelot, Rama Govindarajan +1
The shape assumed by a slender elastic structure is a function both of the geometry of the space in which it exists and the forces it experiences. We explore by experiments and the…
Virus transmission by aerosol transport during short conversations
Rohit Singhal, S. Ravichandran, Rama Govindarajan +1
Pathogens like the SARS-CoV-2 are transmitted not only through violent expiratory events like coughing, but also through routine activities like breathing/speaking/singing. We perf…
Surface tension as the destabiliser of a vortical interface
Rashmi Ramadugu, Prasad Perlekar, Rama Govindarajan
We study the dynamics of an initially flat interface between two immiscible fluids, with a vortex situated on it. We show how surface tension causes vorticity generation at a gener…
Fluid dynamics in clouds: The sum of its parts
S. Ravichandran, Jason R. Picardo, Samriddhi Sankar Ray +1
This entry is aimed at describing cloud physics with an emphasis on fluid dynamics. As is inevitable for a review of an enormously complicated problem, it is highly selective and r…
