Summary
Experimental results concerned with drag reduction by polymer additives in fully developed turbulent pipe flow are presented. Polystyrene samples with low dispersity dissolved in toluene were investigated. The Toms phenomenon is related to a reduction in bursting rate thus diminishing the production of turbulence. A Deborah number is defined as quantitative expression corresponding to the mechanism of drag reduction described.
