Abstract

The decay of turbulence behind a towed grid is studied in polymer and surfactant solutions with the use of particle image velocimetry. Unlike in water, the turbulent energy components show marked anisotropy, and decay more slowly. These differences are stronger for initial periods of time, but persist through the entire period of decay. The major difference between the polymer and surfactant solutions is that the small scales are more strongly damped in the former.
