Laser Velocimeter Measurements of Solids in Multiphase Flow: Technical Progress Report for the Period March 1, 1988-May 31, 1988

摘要

Preliminary tests were conducted using water as the fluid in the refractive index matched multiphase flow loop. Laser Doppler Velocimeter was used for measuring the fluid velocity along a horizontal diameter located 17 feet downstream of the pump. The tests were conducted in the Reynolds number range of 1000 to 3000. In addition to LDV velocity measurements, pressure drops as well as flow rates were also measured. Representative velocity profiles and pressure drop data are presented. The test loop was then filled with the refractive index matched fluid, 55% (by weight) sodium iodide solution in water. The velocity profile for a representative data point and pressure drop data is shown. 5 figs. (ERA citation 13:039088)
