使用新的前向/后向散射激光多普勒测速 (LDV) 技术测量了两相流中的气泡和液体速度。使用标准 LDV 光纤探头通过直接反向散射光测量气泡速度。新颖的后向反射器和透镜组件允许同一探头利用直接前向散射光测量液体速度。初步结果表明该技术在窄厚度尺寸的管道中的有用性。
Measurements of bubble and liquid velocities in two-phase flow have been made using a new forward/backward scattering Laser Doppler Velocimetry (LDV) technique. A standard LDV fiber optic probe was used to measure the bubble velocity using direct backscattered light. A novel retro-reflector and lens assembly permitted the same probe to measure the liquid velocity with direct forward-scattered light. Preliminary results show the usefulness of the technique in a duct of narrow thickness dimension.
