MEASUREMENTS OF TWO-POINT VELOCITY CORRELATIONS IN A PIPE FLOW USING LASER ANEMOMETERS
The purpose of the study has been to develop a laser anemometer system with the capability for measuring the instantaneous velocity at a point in a turbulent flow, and to use this device for the measurement of two-point velocity correlation functions. In the investigation a 0.025 m diam pipe was used with a test medium of water in which was suspended a dilute concentration of small polystyrene latex spheres as scattering particles. Measurements of velocity correlations, mean velocity profiles and turbulence intensities were made at Reynolds numbers ranging from slightly above transition up to 18,100.
