摘要
利用计算流体动力学(CFD)技术,对有机污染物在空间滤波器内的扩散情况进行了数值模拟,得到了在不同洁净控制设计方案下,有机污染物物在空间滤波器真空系统中随扩散时间的浓度分布情况,而后在优选设计的基础上对模型进一步优化,最终减少了有机污染物对空间滤波器内光学元器件的污染,对于实现高功率激光装置的高效、精密运行具有重要意义。
Abstract
By simulating the diffusion of organic contaminants in the spatial filter with the method of computational fluid dynamics(CFD), the concentration distribution of organic contaminants,in different diffusion times and design models, are got in the spatial filter. Then the model is further optimized on the basis of a preferred design. Ultimately the chance that the organic contaminating optical components is reduced.It has important significance to realize the high power laser system efficient and precise operating.
