The application of two-component interferometry is described for the spatially-resolved measurement of particle size, velocity and mass flux as well as continuous phase velocity. Such a capability is important to develop an understanding of the physical processes attendant to two-phase flow systems, especially those involving liquid atomization typical of a wide class of combustion systems. Adapted from laser anemometry, the technique (phase Doppler interferometry) measures single particle events at a point in the flow. Droplet size is deduced from the spatial phase shift of the Doppler signal. Combined with conventional laser anemometry for the resolution of ve...
