Understanding viscoelastic flow instabilities: Oldroyd-B and beyond
Hugo A. Castillo Sanchez, Mihailo R. Jovanovic, Satish Kumar +4
The Oldroyd-B model has been used extensively to predict a host of instabilities in shearing flows of viscoelastic fluids, often realized experimentally using polymer solutions. Th…
Model-based design of riblets for turbulent drag reduction
Wei Ran, Armin Zare, Mihailo R. Jovanović
Both experiments and direct numerical simulations have been used to demonstrate that riblets can reduce turbulent drag by as much as , but their systematic design remains an…
Stochastic dynamical modeling of turbulent flows
Armin Zare, Tryphon T. Georgiou, Mihailo R. Jovanović
Advanced measurement techniques and high performance computing have made large data sets available for a wide range of turbulent flows that arise in engineering applications. Drawi…
Transient growth analysis of oblique shock wave/boundary-layer interactions at Mach 5.92
Anubhav Dwivedi, Nathaniel Hildebrand, Joseph W. Nichols +2
We study physical mechanisms that trigger transient growth in a high-speed spatially-developing laminar boundary layer that interacts with an oblique shock wave. We utilize an appr…
Reattachment streaks in hypersonic compression ramp flow: an input-output analysis
Anubhav Dwivedi, G. S. Sidharth, Joseph W. Nichols +2
We employ global input-output analysis to quantify amplification of exogenous disturbances in compressible boundary layer flows. Using the spatial structure of the dominant respons…
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…
