1. Modal Decomposition of Separated Nozzle Flow
Sammanfattning : The applicability of two different eigenvalue algorithms coupled with an axisymmetric RANS solver to predict the eigenmodes of separated supersonic flow inside an axisymmetric convergent-divergent nozzle was investigated. These are the Arnoldi and the Dynamic Mode Decomposition (DMD) algorithms, respectively. LÄS MER
2. Modal Analysis of Supersonic Flow Separation in Nozzles
Sammanfattning : Operating a convergent-divergent nozzle under overexpanded conditions can lead to supersonic flow separation in the divergent section of the nozzle. In this case, an attached oblique shock wave forms at the separation base. LÄS MER
3. Krylov Subspace Methods for Linear Systems, Eigenvalues and Model Order Reduction
Sammanfattning : New variants of Krylov subspace methods for numerical solution of linear systems, eigenvalue, and model order reduction problems are described. A new method to solve linear systems of equations with several right-hand sides is described. LÄS MER
4. An implementation of a parallel rational Krylov algorithm
Sammanfattning : .... LÄS MER
5. Model order reduction in FEMLAB by dual rational Arnoldi
Sammanfattning : .... LÄS MER
