The potential fluctuations appear to be approximately proportional to the longitudinal-velocity fluctuations ux' in the neighborhood of the boundary. Normalized frequency distributions of potential-fluctuation measurements agree with velocity fluctuation data taken by Klebanoff and Laufer with a hot-wire anemometer at a dimensionless distance y/δ ∼- 10-3 from the wall. Assumptions made concerning the relationship between potential and velocity fluctuations give a possible explanation of the change in the shape of the potential-fluctuation spectrum with the flow velocity and the electrical conductivity of the water. Further analysis is required to establish a definite relationship between electrokinetic-potential fluctuations and velocity fluctuations occurring near a solid boundary.reportsengCopyright and other restrictions may apply.
