2. Psychology of Sport Injury : Prediction, Prevention and Rehabilitation in Swedish Team Sport Athletes
Sammanfattning : The dissertation consists of five separate studies that all have focused on different aspects of the relationship between psychological factors and sport injuries.In the first study the aim was to investigate female elite soccer players’ experiences of the time prior to the occurrence of an ACL injury. LÄS MER
3. Numerical studies of transtion in wall-bounded flows
Sammanfattning : Disturbances introduced in wall-bounded flows can grow and lead to transition from laminar to turbulent flow. In order to reduce losses or enhance mixing in energy systems, a fundamental understanding of the flow stability and transition mechanism is important. LÄS MER
4. Numerical prediction of propeller induced hull pressure pulses and noise
Sammanfattning : An operating marine propeller is one of the major sources inducing hull pressure pulses, onboard noise and vibration as well as underwater radiated noise. There are rising concerns of environmental impacts and comfort and welfare of passengers and crews due to these negative effects. LÄS MER
5. Prediction of Wing Section Lift and Drag from Numerical Solutions of the Navier-Stokes Equations
Sammanfattning : A Navier-Stokes finite difference method is developed and applied to two-dimensional, incompressible, viscous flow around wing sections at medium to high Reynolds numbers. An important feature of such flows is laminar boundary layers with spatially amplified Tollmien-Schlichting waves initiating transition to turbulence. LÄS MER
