AI Technical Summary
Existing technologies struggle to accurately obtain the two-dimensional temperature field of the insulating medium surface of the plasma actuator and the air above the actuator using a single method, resulting in incomplete measurement data.
Fluorescent thermometry is used to acquire fluorescence images by applying a temperature-sensitive coating layer on the surface of the heat-conducting sheet. The two-dimensional surface temperature field is calculated by combining the calibration relationship between light intensity and temperature. The two-dimensional heat source temperature field is then reconstructed by solving a system of linear equations and the least squares method. Finally, the three-dimensional heat source temperature field is reconstructed.
It achieves complete temperature field data for the exciter plasma, the surface of the insulating medium, and the air above, and can accurately obtain the temperature field of the two-dimensional surface and the three-dimensional heat source, supporting the development of aircraft.
