1. Analysis of the Base Wake on Passenger Vehicles
Sammanfattning : Car manufacturers are presented by a continuous increase in fuel prices and by ever more strict legislations regarding CO2-emissions. Decreasing the driving resistance and hence the fuel consumption of their vehicles helps to improvetheir market share. LÄS MER
2. Wind Tunnel Studies of Turbulent Wakes
Sammanfattning : .... LÄS MER
3. Birds in the Flow: Flight Mechanics, Wake Dynamics and Flight Performance
Sammanfattning : I share my fascination of bird flight with many others, and here I summarise my thesis on the subject. This thesis emphasises the mechanics of bird flight by focusing on flight mechanics, wake dynamics and flight performance. LÄS MER
4. Numerical computations of wind turbine wakes and wake interaction : Optimization and control
Sammanfattning : In the present thesis the wake flow behind wind turbines is analyzed numerically using large-eddy simulations. The wind turbine rotors are modeled by using either the actuator disc method or the actuator line method in which the blades are represented by body forces computed with airfoil data. LÄS MER
5. The Axisymmetric Turbulent Wake
Sammanfattning : This thesis presents a theoretical and experimental study of the turbulent axisymmetric wake. In the theoretical part, an equilibrium similarity solution of the far wake was derived that was found to admit to two different solutions for this flow. LÄS MER
