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…
Instabilities in strongly shear-thinning viscoelastic flows through channels and tubes
Ramkarn Patne, Shraddha Mandloi, V. Shankar +1
The linear stability of a shear-thinning, viscoelastic fluid undergoing any of the canonical rectilinear shear flows, viz., plane Couette flow and pressure-driven flow through a ch…
Linear instability of viscoelastic pipe flow
Indresh Chaudhary, Piyush Garg, Ganesh Subramanian +1
A modal stability analysis shows that pressure-driven pipe flow of an Oldroyd-B fluid is linearly unstable to axisymmetric perturbations, in stark contrast to its Newtonian counter…
