Thin-gap averaging of variable-viscosity flows: application to thermoviscous fingering
Dipin S. Pillai, Jason R. Picardo, R. Narayanan
A consistent averaging technique, using the weighted residual integral boundary layer (WRIBL) method, is presented for flow through a thin-gap geometry wherein the fluid's viscosit…
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…
Sedimenting Elastic Filaments in Turbulent Flows
Rahul K. Singh, Jason R. Picardo, Samriddhi Sankar Ray
We investigate the gravitational settling of a long, model elastic filament in homogeneous isotropic turbulence. We show that the flow produces a strongly fluctuating settling velo…
Polymer scission in turbulent flows
Dario Vincenzi, Takeshi Watanabe, Samriddhi Sankar Ray +1
Polymers in a turbulent flow are subject to intense strain, which can cause their scission and thereby limit the experimental study and application of phenomena such as turbulent d…
Dynamics of a long chain in turbulent flows: Impact of vortices
Jason R. Picardo, Rahul Singh, Samriddhi Sankar Ray +1
We show and explain how a long bead-spring chain, immersed in a homogeneous, isotropic turbulent flow, preferentially samples vortical flow structures. We begin with an elastic, ex…
Elasto-inertial Chains in a Two-dimensional Turbulent Flow
Rahul Singh, Mohit Gupta, Jason R. Picardo +2
The interplay of inertia and elasticity is shown to have a significant impact on the transport of filamentary objects, modelled by bead-spring chains, in a two-dimensional turbulen…
