| Abstract: | The object of this contribution is to study the mechanism of dilute polymer solutions drag reduction. A model of polymer agglomerations damping turbulence isdevised. A time-average velocity distribution and a correlation of drag reduction parameter are derived. With the help of those correlations certain drag reduction phenomena can be investigated theoretically. |
