| Abstract: | This paper deals with a helical flow for rheologically complex fluid with yield stress in annulus. By analysing the helical flow theoretically, the conditions for Voscous flow are established and the yield factor is introduced to the viscornitric function. The results obtained by a lot of calculations demonstrated that any difficulty occuring with Saving's method may be avoided. Thus, the present theory of helical flow is developed. |
