1. On stability, transition and turbulence in three-dimensional boundary-layer flows
Sammanfattning : A lot has changed since that day on December 17, 1903 when the Wright brothers made the first powered manned flight. Even though the concepts behind flying are unaltered, appearance of stat-of-the-art modern aircrafts has undergone a massive evolution. LÄS MER
2. Stability and transition of three-dimensional boundary layers
Sammanfattning : A focus has been put on the stability characteristics of different flow types existing on air vehicles. Flow passing over wings and different junctions on an aircraft face numerous local features, ranging from different pressure gradients, to interacting boundary layers. LÄS MER
3. Streak breakdown and transition control in wall-bounded flows
Sammanfattning : .... LÄS MER
4. Reynolds number and freestream turbulence effects on the flow and fluid forces for a circular cylinder in cross flow
Sammanfattning : .... LÄS MER
5. Laninar-turbulent boundary layer transition influenced by free stream turbulence
Sammanfattning : Laminar-turbulent transition in a flat plate boundary layerhas been considered, with a special emphasis on the influencefrom free stream turbulence (FST)First, experiments on linear stability ofTollmien-Schlichting (TS) waves in a Blasius boundary layer wasstudied. This is a well-known example from hydrodynamicstability theory, which has hitherto suffered from unresolveddiscrepancies between experiments and linear theory. LÄS MER
