Turbulence Measurement Study
The capability of a modified commercially available electromagnetic water current meter was evaluated for measurement of parameters necessary to quantify turbulent flow. Values of turbulence intensity were measured, and Fourier analyses of their oscillograph recordings were performed to obtain the spectral distribution of the energy. Field tests were then conducted at three locations selected on the basis of their differences in flow regime. The results showed that values of turbulent intensity for flows between very high to light turbulence levels ranged from 0.71 to 0.06, respectively, and the Fourier analysis of the data shows the energy to be concentrated generally below 5 Hz. This instrument can be used to obtain relative values of turbulent intensity and spectral information from field measurement.
