LIMITING CONDITIONS TO SIMILARITY-LAW CORRELATIONS FOR DRAG-REDUCING POLYMER SOLUTIONS

Similarity-law correlations for drag-reducing polymer solutions are shown to require sufficiently thick turbulent shear layers. Limiting conditions occurring for the shear layers thinned down to only a laminar sublayer and an interactive (buffer) sublayer are examined on the basis of an interactive logarithmic law. Subcritical and supercritical regimes are defined on the basis of shear layer thickness. (Author)
