Identifying spatially-localized instability mechanisms using sparse optimization
Talha Mushtaq, Maziar S. Hemati
Recent investigations have established the physical relevance of spatially-localized instability mechanisms in fluid dynamics and their potential for technological innovations in f…
Structured Input-Output Modeling and Robust Stability Analysis of Compressible Flows
Diganta Bhattacharjee, Talha Mushtaq, Peter Seiler +1
The recently introduced structured input-output analysis is a powerful method for capturing nonlinear phenomena associated with incompressible flows, and this paper extends that me…
Exact Solution for the Rank-One Structured Singular Value with Repeated Complex Full-Block Uncertainty
Talha Mushtaq, Peter Seiler, Maziar S. Hemati
In this note, we present an exact solution for the structured singular value (SSV) of rank-one complex matrices with repeated complex full-block uncertainty. A key step in the proo…
Estimating Regions of Attraction for Transitional Flows using Quadratic Constraints
Aniketh Kalur, Talha Mushtaq, Peter Seiler +1
This letter describes a method for estimating regions of attraction and bounds on permissible perturbation amplitudes in nonlinear fluids systems. The proposed approach exploits qu…
Reducing transient energy growth in a channel flow using static output feedback control
Huaijin Yao, Yiyang Sun, Talha Mushtaq +1
Transient energy growth of flow perturbations is an important mechanism for laminar-to-turbulent transition that can be mitigated with feedback control. Linear quadratic optimal co…
