Transition in elastic Dean flow: the centre-mode versus hoop-stress pathways
P. S. D. Surya Phani Tej, Ganesh Subramanian, V. Shankar
We analyse the stability of viscoelastic Dean flow (flow of an elastic fluid through a curved two-dimensional channel, driven by an azimuthal pressure gradient) in the absence of f…

Nature of continuous spectra in wall-bounded shearing flows of FENE-P fluids
Pratyush Kumar Mohanty, P. S. D. Surya Phani Tej, Ganesh Subramanian +1
Owing to the spatially local nature of the constitutive equations typically used to model polymeric stresses, the differential operators governing the linearized dynamics of bounde…

Inertial migration of slender prolate and thin oblate spheroids in plane Poiseuille flow
Prateek Anand, Ganesh Subramanian
We theoretically examine the inertial migration of a neutrally buoyant spheroid of aspect ratio in wall-bounded plane Poiseuille flow at small particle Reynolds number (…
