Abstract
A planar velocity measurement system ( ) is operative to measure all three velocity components of a flowing fluid ( ) across an illuminated plane ( ) using only a single line of sight. The fluid flow is seeded with small particles which accurately follow the flow field fluctuations. The seeded flow field is illuminated with pulsed laser light source ( ) and the positions of the particles in the flow are recorded on CCD cameras ( ). The in-plane velocities are measured by determining the in-plane particle displacements. The out-of-plane velocity component is determined by measuring the Doppler shift of the light scattered by the particles. Both gas and liquid velocities can be measured, as well as two-phase flows.
