Flow of an Oldroyd-B fluid between intersecting planes Academic Article uri icon

abstract

  • We have studied the non-radial flow of an Oldroyd-B fluid between intersecting planes. The effects of the Reynolds number Re and the elastic number σ are carefully delineated. Our results agree with the results of Strauss (Acta Mechanica, 21 (1975) 141) when σ = 0. In addition to studying the problem when σ ≠ 0, we carried out studies for values of Reynolds number which are two orders of magnitude larger than in previous studies. We find that there is an interesting structural change in the streamline patterns with changes in the Reynolds and Weissenberg numbers which was not observed in the earlier studies, and this has been documented for the first time. © 1993.
