超音速化学氧碘激光器的流场与光场耦合仿真
Coupling Simulation of Flow and Optical Fields in Supersonic Chemical Oxygen-Iodine Lasers
摘要
利用计算流体软件耦合了几何光学模型，并编译了相应的执行程序，数值模拟了超音速化学氧碘激光器（SCOIL）光场从初始建立到稳定过程中流场及光场的衍变情况，解析了功率提取过程对化学流场的动态影响，并将计算结果与实验测量数据进行了对比验证。初步实现了化学氧碘激光器内流场、化学场以及光场的实时耦合仿真，为化学激光器的光束质量、功率水平等一系列重要指标提供直接判据。
Abstract
In order to formulate a numerical procedure and develop a computer program, a solution for the coupled flow-optics interaction problem involving detailed fluid mechanics and geometric optics is proposed. The numerical results are validated through experiment. The corresponding results are available for the analysis and evaluation of the beam quality and power extraction in chemical oxygen-iodine laser devices. It can provide direct criterion for key parameters of chemical laser, such as beam quality and power level.
