Resumen

A new reduction domain strategy is applied in the framework of stability analysis for industrial applications. The aim of this work is to investigate if the geometrical approach proposed could be used as alternative or in combination with the numerical techniques that are currently employed for alleviating the prohibitive computational costs associated to the study of the stability of complex aerodynamic ows.Global linear stability analysis has been applied to a NACA0012 airfoil to study the transient bu�et phenomenon. The leading disturbance associated to bu�eting remains located in a inner región of the computational domain, making this problem a perfect test case for the domain reduction strategy presented here. The base ow has been obtained using DLR-TAU code on a �rst �ne mesh (100 chords) while di�erent, smaller meshes have been used to perform the stability analysis. The eigenvalue problem associated to stability has been solved using a Krylov-Schur projection method with direct LU preconditioning. Results show that the reduction in the computational domain is an useful technique to recover disturbances bounded in a particular region of the aforementioned domain.
