| dc.description.abstract | A model is proposed for drag reduction by polymer additives. The model assumes (a) intermittency between polymer—coil agglomerates in the near—wall region; (b) extension of polymer coils in regions where turbulent energy production exceeds a threshold level; (c) a uniform layer of polymer coils on the wall side of the layer of extended polymers ; and (d) a shift of the origin of the logarithmic velocity profile equation from the wall to the wall side of this layer of uniform polymer coils. The model, and predictions based on it, are shown to be compatible with several observed drag reduction phenomena. | en_AU |
