Low temperature radiometry in high-speed two-phase flows

The possibility of high-sensitive, low-temperature infrared radiometry application for solid phase temperature distribution in high-velocity two-phase flows is demonstrated. As an example the data of solid particles temperature measurements in flows of cold gasdynamic spray technique is presented. The suggested method permit to make the reliable measurements of solid particles temperature at the level (40-100) ºС in the flows with M=2,2 and static temperature of gas phase (200-500 ºС).
