Structured input-output analysis of oblique turbulent bands in Waleffe flow
Jino George, Chang Liu
This work employs structured input-output analysis (SIOA) to study Waleffe flow. The SIOA framework employs structured uncertainty to include the componentwise structure of nonline…

An input-output inspired method for permissible perturbation amplitude of transitional wall-bounded shear flows
Chang Liu, Dennice F. Gayme
The precise set of parameters governing the transition to turbulence in wall-bounded shear flows remains an open question; many theoretical bounds have been obtained, but there is…
