An experimental study of the effect of small particles on the fluid turbulence in fully developed flow of air in a horizontal pipe

Measurements of the mean and fluctuating velocities of both the solid and gas phases in a dilute suspension flowing through a 5 in diameter horizontal pipe are presented. Velocity measurements for both phases were obtained using Laser Doppler Velocimetry; signal discrimination was accomplished through application of the Phase/Doppler principle. Measurements were performed in air containing spherical glass beads with a volume-mean diameter of approximately 45 μm and flowing with a mean centerline velocity between 17 and 24 m/s. The glass particles were able to respond to the most energetic turbulent disturbances in the fluid.
