11. Flow field investigation of rotating wheels on passenger cars
Sammanfattning : The importance of aerodynamics of road-going vehicles on the total driving resistance and hence fuel consumption is well known to vehicle manufactures. At present, upper body aerodynamics of passenger cars is relatively well understood. LÄS MER
12. The Aerodynamic Correlation of a Scale Model with a Full Size Car
Sammanfattning : Reducing the Worlds consumption of energy has become an important part of the current political and environmental debate. The reasons are obvious: World population is increasing, continued growth in living standards, finite availability of resources and finally green house gas emissions from energy production have to be brought down to stabilize temperatures.

13. Design, Optimization and Evaluation of a Transonic Aeroelastic Rig
Sammanfattning : The compressor is one of the most essential components of a modern turbomachinery engine. This component is exposed to vibrations that without proper design can damage structural integrity and lead to failure. LÄS MER
14. A vertex-centered discontinuous Galerkin method for flow problems
Sammanfattning : The understanding of flow problems, and finding their solution, has been important for most of human history, from the design of aqueducts to boats and airplanes. The use of physical miniature models and wind tunnels were, and still are, useful tools for design, but with the development of computers, an increasingly large part of the design process is assisted by computational fluid dynamics (CFD).

15. Numerical Investigation of Unsteady Crosswind Aerodynamics for Ground Vehicles
Sammanfattning : Ground vehicles are subjected to crosswind from various origins such as weather, topography of the ambient environment (land, forest, tunnels, high bushes...) or surrounding traffic. LÄS MER
