1. Global stability and feedback control of boundary layer flows
Sammanfattning : In this thesis the stability of generic boundary layer flows is studied from a global viewpoint using optimization methods. Global eigenmodes of the incompressible linearized Navier-Stokes equations are computed using the Krylov subspace Arnoldi method. LÄS MER
2. Developing Computational Tools for Modern Aeroacoustic Research
Sammanfattning : The thesis presents the author s research on numerical methods for Com-putational Aeroacoustics and the development of computational tools with direct applicability in industry. The designers in the gas-turbine industry, require accurate methods for predicting the onset and the frequencies of dangerous (pressure) oscillations, like the ones which typically occur in Lean Premixed Pre-vaporized (LPP) combustors.
