Abstract

The invention relates to a testing device of an oxygen / iodine ultrasonic mixing heat flow field. A high speed CCD camera-based image testing device is adopted for quantitative testing of the mixing condition of a heat flow field of a chemical oxygen-iodine laser (COIL) with ultrasonic iodine injection (a real flow field during operation of the chemical oxygen-iodine laser). The device comprises a mixing flow field testing section, a light filtering device, a high speed CCD camera and a computer data processing system. Through special design of the testing section, the device makes the oxygen iodine mixing flow field visible at a jet pipe outlet along the flow direction in a direction perpendicular to the jet pipe axis; with the combination of the light filtering device, the high speed CCD camera is used for imaging the oxygen / iodine mixing flow field, and quantitative values of parameters related to the flow field mixing are obtained through digital image processing. Through design of a rotating disc, the device enables the attenuation rate of an attenuation sheet to be convenient to adjust, and thus the testing device is suitable for various operation conditions of COIL.

Description

technical field [0001] The invention relates to a test device for an oxygen-iodine supersonic mixed flow field. Its main purpose is to perform on-line image testing of the oxygen / iodine supersonic mixed flow field of the oxygen-iodine chemical laser injected with iodine at supersonic speed. Through a unique filter / attenuation mechanism, the device can meet the oxygen / iodine supersonic mixed heat flow field test of the oxygen-iodine chemical laser under various operating conditions. One of the biggest features of this device is to test the real operating flow field (ie thermal flow field) of the oxygen iodine chemical laser, which makes the test results more valuable for the structural design and parameter research of the oxygen iodine chemical laser. Background technique [0002] The oxygen-iodine mixing process is an important link in the operation of the oxygen-iodine chemical laser (COIL), because the excited state oxygen provides the energy source for COIL, and the iodi...
