| Popis: | The results of the measurement of the surface temperature of a flat plate in a supersonic air-droplet flow are presented. The plate made of duralumin was mounted vertically in the working channel of an aerodynamic setup. The droplets of a liquid (distilled water) were pulverized into an air flow in a plenum chamber through centrifugal atomizers. The mass concentration of the liquid was about 0.36 and 0.27%, the mean droplet diameter according to Sauter was about 110 μm, and the freestream Mach number M = 2.5 and 3.0. The surface temperature was measured by an IR imager. The measured plate surface temperatures for the case of single-phase air flow (without droplets) were compared with those for the air-droplet flow at the same parameters (with respect to the air) in the plenum chamber. To intensify the droplet sedimentation on the plate a shock generator in the form of a wedge was mounted vertically ahead of the plate. |
