4results about How to "Adjust cooling effect" patented technology

The utility model belongs to the technical field of high-temperature flow field pressure testing, and discloses a water-cooled wall surface static pressure probe provided with multiple cooling loops and used for measuring a high-temperature flow field of an aero-engine combustion chamber. The device is characterized by comprising a pressure sensing hole, a fixed external thread, an octagonal prism positioning block, a fixed internal thread, a sensor mounting cavity, eight water outlet channels and eight water inlet channels. Compared with an existing water-cooling pressure probe, the probe can measure the wall surface static pressure of a flow field under the condition that the interference on the flow field is as small as possible, and meanwhile, the water-cooling pressure probe can adjust the cooling effect of each area of the probe. When the wall surface static pressure of a high-temperature flow field of a combustion chamber of an aero-engine is actually measured, the water-cooled wall surface static pressure probe is fixed in a static pressure hole which is formed in the wall surface of the combustion chamber in advance, a pressure sensor is mounted in the probe, and the water-cooled wall surface static pressure probe can measure the wall surface static pressure in the combustion chamber in a 2500K high-temperature environment through the calibration of a shock tube. And the frequency response of the probe exceeds 80 kHz.
