Effect of cavity-induced perturbation interactions on the transitional flow after the trailing edge
Md Rashidul Islam, Yiyang Sun
We investigate the modal and non-modal linear amplification mechanisms in the flow over a subsonic open cavity and their subsequent interactions to identify optimal flow perturbati…

Identification of cross-frequency interactions in compressible cavity flow using harmonic resolvent analysis
Md Rashidul Islam, Yiyang Sun
The resolvent analysis reveals the worst-case disturbances and the most amplified response in a fluid flow that can develop around a stationary base state. The recent work by Padov…
