Modal stability analysis of viscoelastic channel and pipe flows using a well-conditioned spectral method
Gokul Hariharan, Mihailo R. Jovanović, Satish Kumar
Modal stability analysis provides information about the long-time growth or decay of small-amplitude perturbations around a steady-state solution of a dynamical system. In fluid fl…

Worst-case amplification of disturbances in inertialess Couette flow of viscoelastic fluids
Binh K. Lieu, Mihailo R. Jovanović, Satish Kumar
Amplification of deterministic disturbances in inertialess shear-driven channel flows of viscoelastic fluids is examined by analyzing the frequency responses from spatio-temporal b…
