In this work, the linear responses of turbulent mean flow to both harmonic and stochastic
forcing are investigated for supersonic channel flow. Well-established universal relations are …

This work introduces a formulation of resolvent analysis that uses wavelet transforms rather
than Fourier transforms in time. Under this formulation, resolvent analysis may extend to …

In this study we isolate the mechanisms that are separately responsible for amplifying the
two distinct sets of modes that appear in a linearized Navier-Stokes based model for …

This work applies resolvent analysis to compressible zero-pressure-gradient turbulent
boundary layers with freestream Mach numbers between 2 and 4, focusing exclusively on …

The ability of the low-rank approximation of hypersonic turbulent boundary layers
with/without wall cooling is examined with the linear resolvent operator in a compressible …

recently introduced structured input-output analysis method for incompressible flows to the …

An improved resolvent analysis is proposed in the regime of compressible turbulent
boundary layers. To better model nonlinear processes in the input, the resolvent framework …

We investigate the effects of thermal boundary conditions and Mach number on turbulence
close to walls. In particular, we study the near-wall asymptotic behavior for adiabatic and …
