摘要：

In the present paper, a method is proposed and applied in order to increase the size range sensitivity of a Phase-Doppler-Anemometry (PDA) system, allowing simultaneous measurement of size and velocity distributions of continuous and dispersed phases in gaseous, dispersed two phase Glow. Discrimination between the two phases is directly achieved here from the detected phase difference. Design considerations are presented to increase the size range sensitivity of the PDA system to similar to 1:200. Therefore, the optical properties for light scattering of the particles are properly adjusted to the measurement problem by colouring the particles homogeneously. The application of the system is described by measurements of velocity profiles in a zone close to the nozzle of a two phase jet with a tracer to particle diameter range of 1-160 mu m.
