Some characteristics of the particles used in laser anemometry applications at RAE
Abstract
A knowledge of some of the characteristics of the particles used in laser anemometry experiments is of considerable importance if the results obtained are to be interpreted with confidence. Problems associated with the determination of this quantity are discussed, relevant aspects of the scattering of light by spherical particles are briefly summarized and the results of some laboratory experiments are presented. It is shown that the seeding technique used at present, based on a commercial oil-mist generator, gives satisfactory results for most laser anemometry applications of interest.
