OPTICAL ANEMOMETER. VOLUME I. OPERATION AND MAINTENANCE MANUAL.
Abstract
The report describes the theory of operation and construction of an instrument called an optical anemometer, intended to measure the concentration of particulate matter at a point in an air stream. Velocity-concentration correlation functions also can be measured. Volume One describes the system, its operation, and its maintenance. The length of time required for a single such measurement is on the order of 0.01 seconds. By recording the information constituting such a measurement on magnetic tape and repeating the measurement many thousands of times over a period of a minute or more it is possible, by computer processing of the recorded data, to determine not only the mean concentration and mean velocity in a time steady flow but the turbulent intensity in the direction of flow and the correlation function between the flow velocity and the particle concentration in the flow.
