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.
