Sammanfattning : The work presented in this thesis concerns the development of a viscous-inviscid interaction model for prediction of viscous flow properties in aeronautical applications. The inviscid model is based on an existing potential flow model and the thesis thus focuses on the development of a viscous model based on the three-dimensional integral boundary layer equations.

Sammanfattning : Data assimilation arises in a vast array of different topics: traditionally in meteorological and oceanographic modelling, wind tunnel or water tunnel experiments and recently from biomedical engineering. Data assimilation is a process for combine measured or observed data with a mathematical model, to obtain estimates of the expected data. LÄS MER
Sammanfattning : In this thesis, we have investigated the Recursive Projection Method, RPM, as an accelerator for computations of both steady and unsteady flows, and as a stabilizer in a bifurcation analysis.The criterion of basis extraction is discussed. LÄS MER
4. Eigenvalue analysis and convergence acceleration techniques for summation-by-parts approximations
Sammanfattning : Many physical phenomena can be described mathematically by means of partial differential equations. These mathematical formulations are said to be well-posed if a unique solution, bounded by the given data, exists. LÄS MER
