Juli 2004urn:nbn:de:hbz:467-783AcknowledgementI would like to express my gratitude to the people who contributed over the last flve yearsin making this work a success. Firstly, Prof. Dr.-Ing. habil. Wolfram Frank, my \Dok-torvater", who gave me the opportunity to flnish this work in his Institute with his fullsupport, from the flnancial and technical resources to the motivational and methodolog-ical guidance. Beside Prof. Frank, Dr.-Ing. J˜ org Franke provided me with many usefulcomments and acted as a direct guide along the path of knowledge of numerical uid me-chanics. I am also very grateful to Prof. Dr.-Ing. Thomas Carolus for his advice, supportand encouragement, and his acceptance as the co-referee. Many thanks should go to theprevious and present colleagues at the Institute of Fluid- and Thermal Dynamics of theUniversity of Siegen, Dr.-Ing. Johannes Alken, Dr.-Ing. Gabor Janiga, and Dipl.-Phys.Ing. Hermann Geppert for their friendly help. I would like to acknowledge the DAAD(German Academic Exchange Service) for their flnancial support at the beginning of thiswork.
