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…

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…
