Abstract
The present contribution continues earlier efforts in the area of linear analysis and control of instabilities of flows in complex geometries, via numerical solutions of the appropriate BiGlobal eigenvalue problems (EVP). Experience obtained with the standard Taylor-Hood Finite-Element Methodology (FEM) suggests the need to consider high-order accurate spatial discretization of the EVP solution, in order to mitigate the extreme resolution demands of the low-orded approach. Here work is reported on the first-ever application of an hp-FEM methodology to solve the incompressible BiGlobal EVP. Validation cases, using well-known one- and two-dimensional basic states are presented, which demonstrate the substantial memory and CPU-time savings obtained by application of the present high-order method.
