Turbulent diffusion in high molecular weight additive solutions was measured and compared on a laboratory scale by observing the axisymmetric spreading of a cylindrical turbulent cloud in these solutions of various concentrations. Significant suppression of turbulence in additive solutions was observed. The trend of the results as a function of additive concentrations is similar to that of the additive reduction of turbulent frictional resistance.
