DEVICE FOR DETERMINATION OF HEAT FLOWS AND PRESSURE IN HIGH-TEMPERATURE HIGH-PRESSURE JETS Russian patent published in 2020 - IPC G01K17/16 G01L9/00 

FIELD: physics.

SUBSTANCE: proposed invention relates to experimental aerogasdynamics, in particular to designing devices for determining value of heat flows and pressure on surfaces of models in high-temperature and high-pressure jets. Proposed device consists of heat-absorbing semi-sphere made from highly heat-conducting metal (copper) with central drainage hole. Internal wall of heat-absorbing hemisphere has spiral-like slots. Heat-absorbing hemisphere is tightly welded to the device body by a wall. Supply channel of heat-absorbing liquid in device housing is arranged at an angle and tangentially to internal wall of hemisphere. Housing in the zone of the supply hole has a guide segmental edge coupled with the inner surface of the hemisphere, and discharge channel is connected to annular cavity in housing front part. Device design ensures rationally arranged flow of heat-absorbing liquid washing inner wall of hemisphere, high level of heat exchange and efficient heat removal from internal wall of hemisphere. This ensures efficiency and reliability of the device at higher levels of heat flows acting on the outer surface of the hemisphere.

EFFECT: increased accuracy of measurements and increased range of determined heat flows.
