Orientation dynamics of a spheroid in the simple shear flow of a weakly elastic fluid
Pavan Kumar Singeetham, Deepak Madival, Piyush Garg +1
We investigate the orientation dynamics of a neutrally buoyant spheroid, of an arbitrary aspect ratio (), freely rotating in a weakly viscoelastic fluid undergoing simple shear…

Scalar transport from deformed drops: the singular role of streamline topology
Pavan Kumar Singeetham, Sumesh P Thampi, Ganesh Subramanian
We examine scalar transport from a neutrally buoyant drop, in an ambient planar extensional flow, in the limit of a dominant drop phase resistance. For this interior problem, we co…

Dilute dispersion of compound particles: deformation dynamics and rheology
Pavan Kumar Singeetham, Chaithanya K. V. S., Sumesh P. Thampi
Compound particles are a class of composite systems in which solid particles encapsulated in a fluid droplet are suspended in another fluid. They are encountered in various natural…
