1. Analysis of the Base Wake on Passenger Vehicles
Abstract : 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. READ MORE

2. Analysis of the Unsteady Flow Field of a Passenger Vehicle
Abstract : Political legislation and consumer requirements for a sustainable society require that vehicle manufacturers focus on reduced fuel consumption and lower emissions. Areduction in the overall energy consumption can be directly linked to a decrease of the driving resistance, where the aerodynamic drag significantly contributes at velocities above 70km/h. READ MORE

3. Altered sleep/wake patterns and circadian rhythms : laboratory and field studies of sympathoadrenomedullary and related variables
Abstract : Six studies on sleep/wake patterns and circadian rhythms were carried out. In summary: (1) Adrenaline excretion, self-rated activation, and body temperature rhythms persisted during sleep deprivation, resisted adjustment to rotating shift work, but adjusted rather well to permanent night work.

4. The Axisymmetric Turbulent Wake
Abstract : 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. READ MORE

5. Experimental design and vortex analyses in turbulent wake flows
Abstract : A new experimental setup for studies on wake flow instability and its control that successfully has been designed and manufactured, is introduced and de- scribed. The main body is a dual-sided flat plate with an elliptic leading edge and a blunt trailing edge. READ MORE
