Convective scalar transport from spherical drops in complex shearing flows
Sabarish V. Narayanan, Ganesh Subramanian
We calculate the scalar transport rate, as characterized by the Nusselt number\,(), from a neutrally buoyant spherical drop in an ambient linear flow, in the absence of inertia…
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…
The orientation dynamics of a massive ellipsoid in simple shear flow
Giridar Vishwanathan, Sangamesh Gudda, Ganesh Subramanian
The orientation dynamics of a massive rigid ellipsoid in simple shear flow of a Newtonian fluid is investigated in detail. The term `massive' refers to dominant particle inertia, a…
The flow field due to a sphere moving in a viscous, density stratified fluid
Ramana Patibandla, Anubhab Roy, Ganesh Subramanian
We study the flow field induced by a sphere translating in a viscous density-stratified ambient, specifically, in the limit of small Reynolds , and viscous Ri…
A viscous drop in a planar linear flow -- the role of deformation on streamline topology
Sabarish V. Narayanan, Ganesh Subramanian
Planar linear flows are a one-parameter family, with the parameter being a measure of the relative magnitudes of extension and vorticity; , and…
