Stability and Resolvment Analysis of Plane Couette Flow in the Distinguished Limit Re → ∞,α → 0 WITH Re ·α = O(1).

Konferenzveröffentlichung, Bibliographie
Kurzbeschreibung (Abstract)
In this work the plane Couette flow is being investigated for high Reynolds numbers Re → ∞ and small streamwise wavenumbers α → 0 in the distinguished limit Reα = Reα = O(1) using the temporal linear stability theory as well as the resolvent analysis approach. The influence of Reα on both the eigenfunctions obtained from the linear stability theory and the repsonse modes obtained from the resolvent analysis is investigated, while both modes are being compared in order to analyse the occurence of streamwise-elongated coherent structures within the plane Couette flow.
