Well-conditioned ultraspherical and spectral integration methods for resolvent analysis of channel flows of Newtonian and viscoelastic fluids
Gokul Hariharan, Satish Kumar, Mihailo R. Jovanović
Modal and nonmodal analyses of fluid flows provide fundamental insight into the early stages of transition to turbulence. Eigenvalues of the dynamical generator govern temporal gro…
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…
Amplification of localized body forces in channel flows of viscoelastic fluids
Gokul Hariharan, Mihailo R. Jovanović, Satish Kumar
The study of nonmodal amplification of distributed body forces in channel flows of viscoelastic fluids has provided useful insights into the mechanisms that may govern the initial…
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…
Frequency responses of streamwise-constant perturbations in channel flows of Oldroyd-B fluids
Nazish Hoda, Mihailo R. Jovanović, Satish Kumar
Non-modal amplification of disturbances in streamwise-constant channel flows of Oldroyd-B fluids is studied from an input-output point of view by analyzing the responses of the vel…
Nonmodal amplification of stochastic disturbances in strongly elastic channel flows
Mihailo R. Jovanović, Satish Kumar
Nonmodal amplification of stochastic disturbances in elasticity-dominated channel flows of Oldroyd-B fluids is analyzed in this work. For streamwise-constant flows with high elasti…
