Descriptions
The present paper presents the results of experimental study of the turbulent round jet in dilute polymer solutions. The turbulence characteristics were measured by means of the tracer particle visualization technique. Experimental results show a drastic suppression of small scale turbulence and the increase of integral scale. The anisotropic increase of integral scales in a submerged jet was observed, which implied the strong relationship of the polymer additive with the local turbulent dissipation.
