【Abstract】 Applying the technology of digital image computer, a real time system for collecting and measuring the thermal image of the turbulent flame was developed. Study on the thermal image characteristics of turbulent flame was carried out experimentally and theoretically on a small scale combustion setup and the laws of the thermal image characteristics of turbulent flame were acquired. This paper also presented a method named monochromatic based point temperature calibration which solved the map between the characteristics of flame image and the temperature distribution and surveyed the correction of temperature distortion resulted from radiation overlap when measuring the 3 D temperature field using this method.更多还原
