Abstract

The invention relates to a testing method of an oxygen/iodine ultrasonic mixing heat flow field. Based on the characteristics of the oxygen/iodine ultrasonic mixing heat flow field in a chemical oxygen-iodine laser, with a high speed camera, a testing method of an oxygen/iodine ultrasonic mixing heat flow field is established. The testing method mainly comprises two parts: one part is to establish a set of experimental testing methods through a light filtering attenuating device based on the spectral component characteristics in an oxygen/iodine mixing heat flow field; the other part is to define a series of parameters for flow field quantitative evaluation according to the requirements of oxygen/iodine mixing heat flow field research and based on images obtained by the above experimental testing methods, to provide values of various quantitative parameters under various experimental conditions by a digital image processing program, and to perform quantitative evaluation of the developing process of the oxygen iodine ultrasonic mixing flow field in the chemical oxygen-iodine laser. The method is simple in structure, and easy to realize.
