1. Numerical and Experimental study of shock boundary layer interaction in unsteady transonic flow
Sammanfattning : A prerequisite for aeroelastic stability prediction inturbomachines is the understanding of the fluctuatingaerodynamic forces acting on the blades. Unsteady transonicflows are complex because of mutual interactions betweentravelling pressure waves, outlet disturbances, shock motion,and fluctuating turbulent boundary layers. LÄS MER
2. Neuromechanical control of the spine
Sammanfattning : Control of the spine is complex. The spine is inherently unstable and dependent on the contribution of muscles. Yet there is considerable redundancy in the motor system with many muscles that act on the trunk. LÄS MER
3. On Parameter Identification for Better Predictions of Dam Behaviour
Sammanfattning : Numerical modelling is often needed as a tool to predict the behaviour and assess the safety of dam structures. Embankment dam structures analyses are quite complex and potential failures are hazardous. Predictions of dam behaviour by numerical modelling rely on knowledge about the mechanical properties of the materials the dam is constructed with. LÄS MER
