Design and operation of a light-scattering device for sizing and velocimetry of large droplets
Abstract
The design and operation of a light scattering device for sizing and velocimetry of large droplets are presented. This device was for use as a laboratory standard instrument to compare alternative cooling tower drift measurement methods. The instrument consists of coupled optical and electronic subsystems. Novel beam shaping methods are employed and electronic modules are incorporated into the signal processing chain. The instrument is also capable of droplet velocity measurements, and it is equipped with a fast, online, data reduction capability. The theory of light scattering by large water droplets and instrument calibration procedures are described.
