Summary:

Optical observation of velocity and size of water droplets in powerplant steam has several applications. These include the determination of steam wetness fraction, mass flow rate, and predicting erosion of turbine blades and pipe elbows. The major advantages of optical techniques are that they do not interfere with the flow or perturb the observation. This paper describes the measurement of the size and velocity of particles based on the observation and analysis of visibility patterns created by backscattered circularly polarized light. The size of latex particles in a dry nitrogen stream was measured in the laboratory. Visibility patterns of water droplets were observed in the low pressure turbine of Unit 6 of Alabama Power`s Gorgas Steam Plant.
