EgbersTo my mother, my wife, my children,the memory of my father,and to my ProfessorsABSTRACTIn this thesis, fully developed, turbulent channel o ws with smooth walls, withone rough and one smooth wall and with two rough walls, were studied, providingsome useful and extended information about these kinds of o ws.Fully developed, turbulent plane smooth channel o ws were studied theo-5retically and experimentally. A Reynolds number range up to 1.1 10 wascovered. The value of the von K arm an constant, , was found to be 1=e forthis kind of o w, con rming the recent ndings of Zanoun and Durst [2003].Similarity conditions between channel o ws with smooth surfaces, which possessdi eren t dimensions, were investigated theoretically. Experiments were carriedout to check the theoretical ndings and very good agreement was obtained.Another objective of the present work concerned fully developed, turbu-lent plane channel o ws with one rough and one smooth wall.
