EXPERIMENTS ON FREE TURBULENCE IN VISCO-ELASTIC FLUIDS.

Abstract

In order to investigate the possible turbulencedamping characteristic of non-Newtonian fluids, the diffusion and decay of free turbulence was measured and compared on a laboratory scale by observing the spreading of a cylindrical turbulent wake in different media. Significant changes in the diffusion and decay characteristics of nonNewtonian additives (macromolecules) were observed. The results indicate a close correlation between effects on the decay of turbulence and the reduction of frictional resistance on smooth surfaces as observed in other experiments. (Author)
