A new instability driven by the combined effect of wind stress and rotation in a sheared liquid layer
S. Preethi, Ankush Kamboj, Ramkarn Patne +2
We examine the linear stability of a shear flow driven by wind stress at the free surface and rotation at the lower boundary, mimicking oceanic flows influenced by surface winds an…
Exacerbation of viscoelastic instability due to viscous heating
Ankush Kamboj, Ramkarn Patne, P. A. L. Narayana +1
The linear stability analysis of the pressure-driven flow of an Oldroyd-B fluid through a plane channel is performed to examine the effects of viscous heating-induced buoyancy on t…
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…
Stability of elastoviscoplastic plane Couette flow
Ramkarn Patne
Several studies have investigated the turbulent flow of elastoviscoplastic (EVP) fluids, which exhibit yield stress in addition to viscoelasticity. The instabilities that could be…
Stability of an inviscid flow through a tube with porous wall
Ramkarn Patne
The temporal stability of an inviscid flow through cylindrical geometries with a porous wall subjected to non-axisymmetric perturbations is investigated in the present work using a…
