Phase 1 was a study of the application of magnetohydrodynamic (MHD) techniques to the measurement of turbulence in the flow of water in pipes. A three element probe was developed permitting the simultaneous measurement of the axial and radial components of the turbulent velocities. The effect of probe electrode spacing was studied. The induced emf signals were analyzed by a Hybrid computer to give turbulence intensities, energy spectra, and various correlations for a wide range of Reynolds number. It was concluded that the MHD probe is a very satisfactory device for studying the phenomena of turbulent flow. Phase 2 was a study of the structure of turbulence of a 2-D jet of water impinging into a stagnant body of water. The theoretical phase developed expressions for the mean and turbulent velocity distribution. The experimental phase measured mean and turbulent velocities, energy spectra, and various correlations, using analogous MHD techniques, as in Phase 1. It was concluded that the turbulence characteristics for water were similar to those for air, but the water intensities were about 1/3 those of air. Phase 3 was a study of the portable MHD drogue-LIKE MEAN AND TURBULENT VELOMETERS. The AC, low-gauss magnet used in the mean velometer permitted measurement of mean velocities down to 0.004 fps. It was concluded that this device is competitive with and potentially better than the traditional vane and bucket type of velometers. (Author)
