Abstract
Turbulence can be generated by oscillating a grid in a volume of water. The turbulent flow thus created has minimal mean shear and mean flow. We have studied the motion of small floating particles on the surface of such a turbulent fluid, as well as the velocity fluctuation in the volume of the fluid. For the surface motion, the standard deviation of the velocity difference of a pair of particles separated by a distance R can be fitted by log(R/R 0). That is in contrast to the volume measurements where the data are fitted by a power law. Nevertheless, our result is not explainable by present theories.
