A measurement of a wave front speed of fast processes by a multichannel pyroelectric detector

Experimental technique and devices

The problems connected with application of optical methods anemometry of two-phase flows are considered. The block diagram of the computerized multichannel system of registration of thermal radiation of two-phase flows on pyroelectric detectors is resulted. The principle of operation of system and its functional blocks is described. The integrated optical method of measurement of speed of mass transfer in stationary pulse flows is offered and perspectivity of this method on research of operating modes of technological installations of spraying of coatings is shown.
