The study of this methodology is the result of a collaboration between Chalmers University of Technology and Volvo Trucks AB. The results obtained are not only published to enrich the specific scientific community of flow control, but are also used as a cornerstone for the future implementation of active flow control on real vehicles.
The findings reported in this thesis summarize in fact the work flow of almost four years of research. The presented work spans the process from a theoretical verification of the method to a preliminary implementation of an AFC on a real full scale truck cabin.
From this point on, a continued research will be able to integrate and optimize this technology for a larger scale production and finally contribute to the ”zero emission vision” European countries are striving for.
