Abstract

Flow of Giesekus fluids in straight, arbitrary but axially-symmetric non-circular tubes is investigated. The cross-sectional shapes are obtained through a one-to-one continuous mapping of the circular base contour. The primary longitudinal and the secondary fields are elucidated up to and including the third order in the Weissenberg number Wi.
