Multidisciplinary Coupled Simulation of Supersonic Chemical Oxygen-Iodine Lasers

The three-dimensional coupled computation of flow field, chemical field and optical field of supersonic chemical oxygen-iodine lasers is realized. Numerical methods are developed to improve the compatibility of multidisciplinary computation and the effectiveness of data communication. The coupled simulation gives detailed information about the three-dimensional mixing flow in the cavity, the diffraction of resonant optical field, the influence of power extraction upon chemical reacting flow fields, and the intensity and phase distribution of the output beam. The coupled simulation method gives better vision of the physical and chemical processes of COIL and is applicable for the laser performance prediction.
