Исследование процессов смешения парокапельных и высокотемпературных газовых смесей

The diagram, technique and results of series experiments to investigation of processes on the entering of sprayed water into the high-temperature combustion products flow are proposed. Modern highprecision diagnostic equipment operating on the basis of the method digital “tracer” visualization, in particular, PIV (Particle Image Velocimetry) is used for the recording and processing of video frames in experiments. Video frames, histograms and the velocities fields on the entering of vapor-drop mixture spray liquid flow (water with a “tracer” particles of titanium dioxide nanopowder) on the high-temperature gas flow (combustion products) are presented. Effects of turning the trajectory droplets flow, typical for the considered process of mixing are shown. Significant effect of the velocity rising combustion products and sizes of individual droplets of sprayed water flow on the degree of the latter’s ash is established.
